Description

Ethanone, 1-(3-Phenyloxiranyl)-, (2R-Cis)- (9Ci) is a chiral epoxide derivative of acetophenone, serving as a critical chiral building block and synthetic intermediate in advanced organic synthesis. Its defined stereochemistry and reactive oxirane ring make it invaluable for constructing complex molecules with high enantiomeric purity. This compound is primarily needed by research institutions and manufacturers in the pharmaceutical and fine chemical industries for developing active pharmaceutical ingredients (APIs) and specialty chemicals.

Application

• Pharmaceutical Intermediate: Key chiral synthon for the synthesis of novel drug candidates and active pharmaceutical ingredients (APIs), particularly in central nervous system (CNS) and cardiovascular research.
• Asymmetric Synthesis: Used as a precursor in stereoselective reactions to introduce the (2R-Cis)-phenyloxiranyl moiety into target molecules.
• Fine Chemical Production: Employed in the manufacture of specialty chemicals, agrochemicals, and advanced materials requiring specific chiral architectures.
• Academic & Industrial Research: Serves as a standard or starting material in methodological development for ring-opening reactions and epoxide chemistry.
• Ligand and Catalyst Development: Potential use in the synthesis of chiral ligands or organocatalysts for catalytic asymmetric transformations.
