Description

Propyl (S)-(-)-Lactate is a high-purity chiral ester derived from (S)-lactic acid. This optically active compound is a valuable chiral building block and solvent, prized for its role in asymmetric synthesis and as a flavor and fragrance intermediate. It is essential for manufacturers in the pharmaceutical, fine chemical, and flavor & fragrance industries seeking enantiomerically pure materials for advanced applications.

Application

• Chiral Intermediate in Pharmaceutical Synthesis: Used as a key building block for the production of active pharmaceutical ingredients (APIs) requiring specific stereochemistry.
• Asymmetric Synthesis & Catalysis: Serves as a chiral auxiliary or solvent in stereoselective reactions to create enantiomerically enriched products.
• Flavor and Fragrance Ingredient: Imparts characteristic fruity, buttery notes in high-end flavor formulations and fragrance compositions.
• Green Solvent: Employed as a biodegradable and renewable solvent derived from natural sources for specialized chemical processes.
• Polymer Modification: Acts as a monomer or plasticizer in the synthesis of specialized, biodegradable polymers.
• Analytical Chemistry Standard: Utilized as a reference standard for chiral analysis and method development in chromatography.
