Description

Ethanone, 1-[(2R,3S)-3-Butyloxiranyl]- (9Ci) is a specialized chiral epoxide derivative of ethanone, a key synthetic intermediate of high interest in fine chemical and pharmaceutical research. Its precise stereochemistry at the 2R,3S positions makes it a valuable building block for the enantioselective synthesis of complex molecules. This compound is primarily sought by research chemists and process development scientists working in advanced organic synthesis, particularly for the development of active pharmaceutical ingredients (APIs) and other high-value chiral compounds.

Application

• Pharmaceutical Intermediate: A critical chiral synthon for the research and development of novel Active Pharmaceutical Ingredients (APIs), especially in therapeutic areas requiring stereochemical purity.
• Asymmetric Synthesis: Used as a key electrophile or building block in stereocontrolled chemical reactions, including nucleophilic ring-opening and cross-coupling reactions.
• Agrochemical Research: Serves as a precursor in the synthesis of chiral ligands and complex molecules for advanced crop protection agents.
• Fine Chemical Production: Employed in the manufacture of specialty chemicals, flavors, fragrances, and advanced materials where specific stereochemistry is required.
• Academic & Industrial R&D: A valuable reagent for methodological development in organic chemistry and catalysis studies within university and corporate research laboratories.
