L-Diacetyltartaric anhydride (L-DATA) is a high-purity chiral resolving agent and organic synthesis intermediate, featuring an anhydride structure with high reactivity and enantioselectivity. It is a white crystalline solid with excellent solubility in organic solvents, widely used for the chiral resolution of alcohols, amines, and amino acids in pharmaceutical production.

Key Features

· High chiral purity: ≥99.0% enantiomeric excess (e.e.)

· High reactivity in acylation and resolution reactions

· Good solubility in ethyl acetate, toluene, and other organic solvents

· Stable under sealed storage conditions, low hygroscopicity

· Complies with international pharmaceutical quality standards

Pharmaceutical Applications

· Chiral resolution of racemic alcohols, amines, and amino acids for high-purity API production

· Key intermediate for the synthesis of β-lactam antibiotics, including penicillin and cephalosporin derivatives

· Acylation reagent and catalyst for asymmetric synthesis reactions in pharmaceutical R&D

· Resolving agent for the production of cardiovascular drugs, antidepressants, and anti-infective drugs
