Description

(+)-Ethyl D-Lactate CAS NO 7699-00-5 is a high-purity chiral ester of D-lactic acid, serving as a critical chiral building block and solvent in advanced chemical synthesis. Its primary value lies in its enantiomeric purity, which is essential for producing optically active compounds with high stereoselectivity. This product is indispensable for pharmaceutical intermediates, fine chemical manufacturing, and as a specialty green solvent in high-value applications.

Application

• Pharmaceutical Intermediate: Key chiral synthon for the production of active pharmaceutical ingredients (APIs), particularly in antiviral and cardiovascular drug synthesis.
• Asymmetric Synthesis: Employed as a chiral auxiliary or resolving agent in stereoselective organic reactions to control absolute configuration.
• Fine Chemical Production: Used in the manufacture of agrochemicals, flavors, fragrances, and other specialty chemicals requiring high optical purity.
• Green Solvent: Acts as a biodegradable and renewable solvent derived from natural sources for specialized extraction and reaction processes.
• Polymer Chemistry: Monomer or co-monomer for synthesizing biodegradable polymers like polylactic acid (PLA) with specific stereochemical properties.
• Biocatalysis & Enzymatic Reactions: Substrate or product in enzymatic kinetic resolutions and transesterification processes.
