Product Description:

Ethyl L-lactate is the ethyl ester of L-lactic acid. It is a colorless to pale yellow liquid with a characteristic, mild, fruity odor. It is a chiral compound, with the L-enantiomer being the naturally occurring form. Its primary applications are in the flavor and fragrance industries. As a flavoring agent, it imparts a creamy, buttery, or fruity note and is used in various food products, beverages, and dairy items. In perfumery and cosmetics, it serves as a solvent and a fragrance component due to its pleasant odor and good solvent properties for many aromatic compounds. It is also considered a "green" solvent in some applications, being biodegradable and derived from renewable resources. Additionally, ethyl L-lactate is utilized as a chiral building block in organic synthesis, particularly in the pharmaceutical industry for the preparation of more complex chiral molecules. It can also function as a solvent in coatings, inks, and cleaning formulations.
