Description

(S)-3-(Acetyloxy)-2-butanone, also known as 2-Butanone, 3-(Acetyloxy)-, (S)- (9Ci) CAS NO 171287-68-6, is a chiral, acetylated derivative of 2-butanone. This compound serves as a valuable chiral building block and intermediate in sophisticated organic synthesis, particularly for the production of enantiomerically pure pharmaceuticals and agrochemicals. It is essential for research and development chemists in the pharmaceutical, fine chemical, and flavor & fragrance industries who require high-purity, stereochemically defined intermediates.

Application

• Pharmaceutical Intermediate: Key chiral synthon for the synthesis of active pharmaceutical ingredients (APIs) requiring specific stereochemistry.
• Agrochemical Synthesis: Used in the production of enantiomerically pure herbicides, fungicides, and pesticides for enhanced efficacy.
• Fine Chemical Production: Acts as a precursor in the manufacture of complex organic molecules for research and specialty applications.
• Flavor and Fragrance Ingredient: Potential intermediate for creating specific chiral aroma compounds.
• Asymmetric Catalysis Research: Valuable substrate for developing and testing new chiral catalysts and synthetic methodologies.
• Material Science: Intermediate in the synthesis of specialized polymers or liquid crystals with chiral properties.
