Description

(R)-Lactate CAS NO 10326-41-7 is the enantiomerically pure form of lactic acid, a fundamental chiral building block and intermediate in organic synthesis. This high-purity compound is critical for applications requiring specific stereochemistry, such as the production of active pharmaceutical ingredients (APIs) and fine chemicals. It is essential for research and manufacturing in the pharmaceutical, agrochemical, and specialty chemical industries where optical purity directly impacts biological activity and product efficacy.

Application

• Chiral Synthesis: A key starting material and resolving agent for the asymmetric synthesis of pharmaceuticals and agrochemicals.
• Pharmaceutical Intermediates: Used in the production of enantiomerically pure drugs, including various antibiotics and cardiovascular agents.
• Biodegradable Polymers: Serves as a monomer or co-monomer precursor for synthesizing polylactic acid (PLA) and other biocompatible polymers.
• Food & Beverage Additives: Employed as an acidulant and preservative in food-grade applications where the specific (R)-enantiomer is required.
• Cosmetic Ingredients: Used in skincare formulations for its moisturizing and exfoliating properties as part of α-hydroxy acid (AHA) complexes.
• Chemical Research: A standard reagent in academic and industrial R&D for studying enzymatic reactions, chiral catalysis, and metabolic pathways.
