(-)-Dibenzoyl-L-tartaric acid monohydrate

(-)-Dibenzoyl-L-tartaric acid monohydrate (CAS 62708-56-9, EC 613-072-9) is a chiral organic acid derived from L-tartaric acid, with both hydroxyl groups esterified by benzoyl groups. It is also referred to as DI-O-BENZOYL-L-TARTARIC ACID and carries no assigned E-code. No common abbreviation is established in trade literature.

In pharmaceutical manufacturing, it functions as a chiral resolving agent, separating racemic amines into enantiomerically pure salts through selective crystallization. In personal care formulations, it acts as a pH buffer and mild preservative, stabilizing product systems against microbial and oxidative degradation. Its UV-absorbing benzoyl groups also contribute to photostabilization in light-sensitive preparations.

This material is supplied as a powder grade compliant with REACH registration requirements. It is relevant to pharmaceutical workflows requiring documented purity and traceability, and procurement teams should confirm Ph.Eur. or in-house specification alignment prior to ordering. Standard packaging formats follow supplier-specific configurations for laboratory and industrial quantities.
