Description

Oxirane, 2-(1-Hexynyl)-3-Methyl-, (2S-Cis)- (9Ci) is a specialized chiral epoxide building block of significant interest in advanced organic synthesis. Its unique structure, featuring both an alkyne and a methyl-substituted oxirane ring in a defined stereochemical configuration, makes it a valuable precursor for constructing complex, stereodefined molecular architectures. This high-purity intermediate is essential for researchers and process chemists in the pharmaceutical and fine chemical industries who require precise control over stereochemistry in their synthetic routes, particularly for the development of active pharmaceutical ingredients (APIs) and novel materials.

Application

• Pharmaceutical Intermediate: Serves as a key chiral synthon in the asymmetric synthesis of complex drug candidates and active pharmaceutical ingredients (APIs).
• Fine Chemical Synthesis: Used in the research and development of specialty chemicals, agrochemicals, and performance materials where stereochemical control is critical.
• Organic Synthesis Building Block: The reactive epoxide and alkyne functionalities allow for diverse chemical transformations, including ring-opening reactions and click chemistry, enabling the construction of novel molecular scaffolds.
• Ligand and Catalyst Development: Acts as a precursor for synthesizing chiral ligands and organocatalysts used in enantioselective catalysis.
• Material Science Research: Investigated for the preparation of polymers and advanced materials with specific stereoregular properties.
