D-tartaric acid

D-tartaric acid (CAS 147-71-7), also known as D-threaric acid, is the unnatural enantiomer of tartaric acid, distinguished from the naturally occurring L-form by its opposite optical rotation. It functions as a chiral building block, pH regulator, and acidulant across pharmaceutical, cosmetic, and specialty food applications. In pharmaceutical manufacturing, it serves as a chiral resolving agent.

This material is essential for synthesizing enantiomerically pure active ingredients where stereochemical precision is critical. Cosmetic formulators use it as an acidulant and chelating agent in skin care products. It helps stabilize formulations and adjust pH to optimize active ingredient performance. In food and beverage production, it acts as an acidulant and antioxidant synergist, extending shelf life and tartness.

It contributes tartness to confectionery, beverages, and bakery products. Its chelating capacity also makes it effective for sequestering metal ions that would otherwise accelerate oxidative degradation in sensitive formulations. D-tartaric acid is supplied as a white crystalline powder. It is available in pharmaceutical-grade (USP/BP) and food-grade (FCC) specifications to meet regulatory requirements across different industries.

Technical-grade material is also offered for industrial and synthesis applications where compendial certification is not required. This ensures versatility for various manufacturing and laboratory processes.
