Description
Ethyl L-lactate, a ethyl ester of the D-lactic acid that derives from bio-fermentation of sugar-like
carbohydrate, is also featured in high optical purity, Colorless, transparent liquid having
characteristic odor, It is completely miscible with water and most organicsolvents, Hydrolytic
partially in water.
