At a Glance
- Confirm the identity first: PM solvent is commonly identified as PGME, or 1-methoxy-2-propanol, CAS 107-98-2. Include the CAS number in every RFQ.
- Do not rely on similar names: PGMEA/PMA and DPM are related glycol ethers, but they are not interchangeable with PGME.
- Define the application: The required grade and documentation depend on whether the material is intended for coatings, inks, cleaning, or another approved industrial use.
- Compare quotes on the same basis: Packaging, quantity, origin, freight, delivery terms, and documentation can change the real cost of bulk PGME.
- Qualify documents early: Review the current SDS, specification sheet, COA format, and delivery basis before approving a supplier.
- Request a complete quote: Include the application, required specification, quantity, packaging, destination, and document requirements.
What you’ll learn
This guide helps US buyers identify the correct PM solvent, distinguish PGME from adjacent glycol ethers, and request a comparable bulk quotation. It also explains the documents, qualification questions, and delivery details that should be resolved before selecting a supplier.
Introduction
A search for PM solvent can produce results for PGME, PGMEA, PMA, DPM, retail drum listings, and bulk chemical suppliers. These products may be related, but they are not automatically the same material or the right choice for the same formulation.
That creates a sourcing risk. If the buyer requests “methoxy propanol” without a CAS number, a supplier may quote a different glycol ether, or procurement may compare non-equivalent products on price alone. Bulk PM solvent sourcing starts with chemical identity, then moves to application fit, grade, documentation, packaging, and delivered cost.
For buyers seeking a PM solvent specification pack, the first checkpoint is clear: confirm that the required product is propylene glycol monomethyl ether, also called PGME or 1-methoxy-2-propanol, CAS 107-98-2.
Quick answer: how should US buyers source bulk PM solvent?
US buyers should source bulk PM solvent only after confirming the product identity, application, specification requirements, and delivery basis. A retail price, laboratory pack, PGMEA offer, or DPM quote is not a reliable equivalent for a bulk PGME requirement.
The sourcing process should follow three steps:
- Confirm that the requested material is PGME, also called PM solvent, CAS 107-98-2.
- Define the application, technical specification, documents, packaging, quantity, and destination.
- Compare only quotes that match on product, specification, and delivered-cost basis.
This approach avoids a common glycol-ether procurement error: treating similar trade names as chemical substitutes. It also gives formulation, EHS, operations, and procurement teams one shared basis for evaluating the offer.
What is PM solvent?
PM solvent is a common name for propylene glycol monomethyl ether, or PGME. It is also known as 1-methoxy-2-propanol and is identified by CAS 107-98-2.
PGME is a glycol ether used in industrial solvent applications. The US National Institute for Occupational Safety and Health identifies propylene glycol monomethyl ether under the synonyms 1-methoxy-2-propanol and propylene glycol methyl ether, with CAS 107-98-2. NIOSH’s PGME profile provides a useful identity and occupational-safety reference.
PM solvent names and identification
A chemical name alone is not always enough for a procurement request. “Methoxy propanol,” “propylene glycol,” and “PM” may be used loosely in the market, while buyers need confirmation of the exact material before comparing specifications or price.
Use this identity block in an RFQ, technical enquiry, or internal approval request:
Product: Propylene glycol monomethyl ether
Common names: PM solvent, PGME, 1-methoxy-2-propanol
CAS number: 107-98-2
The supplier’s current SDS and specification sheet should be the final confirmation of the material offered. Do not approve a quote based only on a product nickname or a website listing.
Why correct identification matters
The wrong glycol ether can create problems for a formulation, quality system, EHS review, or purchasing agreement. A request that says “PM solvent” but omits CAS 107-98-2 can result in a quote that is difficult to compare or unsuitable for the intended application.
Correct identification also improves the supplier discussion. It allows the buyer to focus on the actual questions that matter: the quality basis, grade expectations, documentation, packaging, logistics, and commercial terms.
PM solvent versus PGMEA/PMA and DPM
PGME, PGMEA or PMA, and DPM are related glycol ethers, not interchangeable labels. Each should be evaluated on its own chemical identity, formulation role, technical documentation, and approval requirements.
The right material depends on the job the solvent must perform within a specific formulation or process. A coatings manufacturer, printing-ink producer, industrial-cleaning formulator, and operations buyer may each have different requirements. Do not choose a glycol ether simply because it appears in the same search result or has a lower listed price.
| Material | Common name | CAS number | Buyer question |
| PGME | PM solvent, 1-methoxy-2-propanol | 107-98-2 | Is this the required solvent and does the offered specification match the approved requirement? |
| PGMEA | PMA, propylene glycol methyl ether acetate | Confirm through current supplier SDS | Does the formulation require the acetate glycol ether instead of PGME? |
| DPM | Dipropylene glycol methyl ether | Confirm through current supplier SDS | Does the process require a different glycol-ether profile and technical review? |
Buyers who need to assess an adjacent product can compare PGME with PGMEA/PMA or consider DPM for a different glycol-ether requirement. These are product-discovery resources, not proof that one material can replace another.
PM solvent grades and application-fit questions
A generic grade label does not define an acceptable PM solvent specification. The buyer must state what the material will do in the process and which quality characteristics are relevant to formulation performance, internal approval, and customer requirements.
Typical industrial use contexts
PGME is used in industrial solvent applications including coatings, printing inks, and industrial cleaning. These categories explain where the material may be evaluated, but they do not establish universal compatibility or suitability.
A coatings formulator may focus on consistency, residue expectations, and the role of the solvent in the complete system. An ink producer may assess a different set of printing, drying, substrate, or process questions. A cleaning-product manufacturer must consider the entire formulation and intended operating conditions.
State the actual application in the RFQ. “Industrial use” is too broad to establish the correct grade, specification, documents, or technical-validation path.
Questions that determine specification suitability
Start with the application, then define the acceptance criteria. This gives the supplier a clear requirement and prevents a generic catalogue description from being treated as a technical approval.
| Qualification field | Buyer requirement | Supplier confirmation |
| Product identity | PM solvent, PGME, CAS 107-98-2 | Identity shown on current SDS and specification |
| Application | Coating, ink, cleaning, or other approved use | Application context for the offer |
| Grade or specification | Buyer-approved requirement | Current specification basis |
| Impurity or water limit | Process-specific criteria | Documentation that addresses the stated criteria |
| Required documents | SDS, COA format, specification sheet, declarations if needed | Documents available for review |
| Packaging | Required packaging and net weight | Offered packaging basis |
| Delivery destination | US location and delivery term | Quote scope and logistics basis |
This is a qualification framework, not a universal PGME specification. Technical values should come from the buyer’s approved requirement and the supplier’s current documents.
What affects bulk PM solvent price in the USA?
There is no single reliable public bulk PM solvent price. Search results often mix small packs, retail listings, PGME, PGMEA, DPM, and supplier pages. Those results may help identify potential suppliers, but they do not give procurement a valid delivered-cost benchmark.
A bulk PGME quote can change with the product specification, order quantity, packaging, origin, freight, delivery destination, delivery term, requested schedule, documentation, payment terms, and quote-validity period. The price is useful only when the scope is clear.
Do not use a PGMEA, DPM, retail gallon, or small-pack price as a negotiation benchmark for bulk PGME. Confirm the correct material first, then compare offers using a consistent quote worksheet.
| Quote component | What to compare |
| Product identity and specification | PGME, CAS 107-98-2, and approved quality basis |
| Quantity and call-off schedule | Total requirement, shipment size, and expected timing |
| Packaging | Package type, net weight, and handling needs |
| Origin and supply route | Supplier role and stated product origin |
| Delivery term and destination | Freight and delivery obligation included in the quote |
| Documentation included | SDS, specification, COA format, and required declarations |
| Quote validity | Commercial validity period |
| Total delivered-cost basis | Material, packaging, freight, and other quoted elements |
If an item is missing from a quote, record it as a gap rather than assuming it matches another supplier’s offer. That is the only way to determine whether an apparently lower price is actually lower on a delivered and qualified basis.
Supplier qualification and documentation checklist
Supplier qualification should connect the chemical identity, technical requirement, commercial route, and receiving-site needs. It is easier to resolve these questions before a sample trial or purchase order than after a shipment is in transit.
- Confirm the material is PM solvent, PGME, CAS 107-98-2.
- Define the application and approved grade or specification requirement.
- Request the current SDS, product specification sheet, and representative COA format.
- Verify the supplier’s role, stated product origin, and traceability approach.
- Confirm packaging, quantity, delivery term, destination, and quote validity.
- Review safety, compliance, and site requirements with the appropriate EHS and regulatory teams.
- Compare equivalent supplier quotes and qualify a representative sample where appropriate.
Buyers managing a broader industrial input portfolio can review chemical-intermediate sourcing requirements. The goal is to produce a technically usable, commercially comparable quote rather than to gather a list of unverified prices.
Safety, storage, and compliance boundaries
PM solvent has occupational-safety and handling considerations that must be reviewed through the current SDS and the receiving site’s EHS process. This guide does not replace approved procedures for storage, transport, exposure control, personal protection, emergency response, or waste management.
NIOSH identifies potential exposure routes that include inhalation, ingestion, and skin or eye contact. Its information provides occupational context, while the supplier’s current SDS and the site’s own approved controls should govern the actual operation.
A chemical identity or US-market reference does not establish suitability for every downstream use. Formulators, EHS teams, and regulatory reviewers should assess the intended application, customer requirements, and destination-specific obligations before the material is approved.

FAQs
- Is PM solvent the same as PGME?
PM solvent is commonly used as a name for propylene glycol monomethyl ether, also called PGME or 1-methoxy-2-propanol. The CAS number is 107-98-2. Include that CAS number in your RFQ because related glycol ethers may appear under similar names in supplier catalogues and search results.
- What is the CAS number for propylene glycol monomethyl ether?
The CAS number for propylene glycol monomethyl ether, commonly called PGME or PM solvent, is 107-98-2. Confirm the number on the supplier’s current SDS and specification sheet before approving a quotation, sample, or commercial shipment.
- Is PGMEA the same as PM solvent?
No. PGMEA, often called PMA, and PGME are related glycol ethers but distinct products. They should not be treated as substitutes based on naming alone. The formulation, required solvent performance, technical documentation, and application validation determine whether either material is appropriate.
- What information is needed for a bulk PM solvent quote?
Provide the product identity and CAS number, application, required specification, quantity, packaging, US destination, delivery term, requested schedule, and documentation needs. This lets the supplier quote the correct material and allows procurement to compare the offer with technically equivalent alternatives.
- How should buyers compare PM solvent supplier quotes?
Compare the chemical identity, specification, quantity, packaging, origin, delivery term, freight basis, documents, quote validity, and total delivered cost. A lower unit price is not necessarily the better commercial result when the offer excludes relevant documentation, packaging, freight, or delivery obligations.
- What documents should accompany a bulk PGME shipment?
The documents commonly reviewed include the current SDS, product specification sheet, and batch COA format. Depending on the buyer’s approval process and destination requirements, additional declarations may also be needed. Confirm document expectations in the RFQ so there is no gap between qualification and shipment.
Conclusion
Bulk PM solvent sourcing is more reliable when product identity is confirmed before price is discussed. Confirm PGME or 1-methoxy-2-propanol as CAS 107-98-2, define the technical requirement, and compare quotes on the same packaging, documentation, and delivery basis.
This process prevents confusion with PGMEA and DPM, while giving procurement a clear path to qualify the right material. For a technical evaluation route, request a sample for qualification.
