About D-Malic Acid
D-Malic acid - D-(+)-malic acid, the (R)-enantiomer of 2-hydroxybutanedioic acid (CAS 636-61-3, C₄H₆O₅, MW 134.09) - is a white crystalline powder with a clean, sharp sour taste. It is the mirror-image form of the malic acid found naturally in apples, valued both as a food acidulant and as a chiral building block for pharmaceutical and fine-chemical synthesis.
Malic acid comes in three forms: L-malic acid (the natural, apple-derived isomer), DL-malic acid (the racemic mixture used as a common food acidulant), and D-malic acid (this product - the D-(+) enantiomer, used where a single, defined chirality is required). As an acidulant it delivers a stronger, longer-lasting tartness than citric acid, letting formulators cut acid use and mask the bitter note of high-intensity sweeteners.
Elchemy is a trusted D-malic acid supplier, manufacturer partner and distributor, supplying food, pharmaceutical and laboratory grades to buyers across 40+ countries, each with a Certificate of Analysis and samples within 24–48 hours.
D-Malic Acid Suppliers, Manufacturers & Distributors

Buy D-Malic Acid in Bulk (White Crystalline Powder)
Elchemy supplies bulk D-malic acid as a white crystalline powder, from laboratory quantities to full commercial volumes, in food, pharmaceutical and technical grades. Tell us your grade, optical purity and volume for a fast quote.
Where to Buy D-Malic Acid
Wondering where to buy D-malic acid in bulk? Elchemy ships worldwide with US domestic stock for faster delivery. Submit the quote form with your grade, purity and volume and we'll confirm availability, price and lead time within 24–48 hours.
D-Malic Acid Price: Bulk Pricing & Price per Kg
As a single-enantiomer specialty acid, the D-malic acid price depends on grade, optical purity, order volume and origin, so Elchemy quotes live rather than publishing a fixed rate.
Buyers benchmark the price per kg for trial lots and the per-drum or per-MT rate for contracts. Request a quote for an exact figure within 24–48 hours.
D-Malic Acid Manufacturing Process
D-malic acid is produced either by enzymatic or microbial conversion of maleic acid, which yields the D-form selectively, or by resolution of racemic DL-malic acid. The crude acid is purified and crystallised to a white crystalline powder meeting the target assay and optical rotation.
Raw materials are maleic or fumaric acid feedstock, water, and a biocatalyst or resolving agent.
Why Choose Elchemy as a Trusted D-Malic Acid Supplier
- Multiple grades - food, pharmaceutical and laboratory D-malic acid from one partner
- Verified purity and chirality - COA confirming assay and optical rotation on every batch
- Samples in 24–48 hours - qualify grade and purity before any bulk order
- Tailored options - specific grades and pack sizes via custom manufacturing
Packaging & Logistics
D-malic acid ships in 25 kg fibre drums or lined bags, palletised for container loads. As a hygroscopic acid, store it sealed in a cool, dry place away from moisture and strong bases.
US domestic stock supports faster delivery, on FOB, CIF or DDP terms.
Safety & Handling
D-malic acid is a mild organic acid and a skin and eye irritant (GHS: causes serious eye irritation). Handlers should wear gloves and goggles, avoid dust, and flush with water on contact. It is not flammable under normal conditions. A full GHS-aligned SDS ships with orders.
- Flavor Enhancement: Provides a tart taste that balances sweetness in food and beverages.
- Function: Flavor enhancer, pH regulator, acidulant, preservative, and chelating agent.
- High Purity Standards: Ensures quality and safety in food, pharmaceuticals, and cosmetics.
- Features: Provides a smooth, lingering sour taste, is highly soluble in water, and has a lower melting point compared to other food acids.
- Eco-Friendly Production: Focus on sustainable manufacturing practices.
- Benefits: Enhances and blends flavors, masks the aftertaste of artificial sweeteners, helps to stabilize color, and can increase product yield in some applications like cheese making. It also plays a role in energy metabolism in the body.
