Product Description
(R)-Lactate (CAS: 10326-41-7), also known as D-lactic acid or (R)-2-hydroxypropanoic acid, is an important chiral organic compound belonging to the carboxylic acid derivative class. It is one of the enantiomers of lactic acid, with specific stereochemical properties that make it widely used in food, pharmaceutical, cosmetic and material industries. As a natural intermediate in sugar fermentation and metabolism, it is also a key raw material for the synthesis of biodegradable plastic polylactic acid. It has a mild acidic property and good solubility, and its high optical purity makes it indispensable in chiral synthesis and pharmaceutical preparation.
