Description

(R)-3-Chlorostyrene Oxide is a high-value chiral epoxide building block characterized by its specific stereochemistry and reactive oxirane ring. This compound matters as a critical intermediate for the synthesis of enantiomerically pure pharmaceuticals, agrochemicals, and advanced materials, where its defined (R)-configuration is essential for biological activity and material properties. It is needed by R&D chemists and process development scientists in the pharmaceutical, fine chemical, and specialty polymer industries for applications in asymmetric synthesis and chiral resolution.

Application

• Pharmaceutical Intermediate: Key chiral synthon for the production of active pharmaceutical ingredients (APIs), particularly in cardiovascular and central nervous system (CNS) drug candidates.
• Agrochemical Synthesis: Used in the manufacture of enantiomerically pure herbicides, fungicides, and plant growth regulators.
• Liquid Crystal & Polymer Chemistry: Serves as a monomer or precursor for chiral dopants in liquid crystal displays (LCDs) and for creating optically active polymers.
• Asymmetric Catalysis Research: Employed as a standard substrate or ligand precursor in the development and screening of new chiral catalysts.
• Fine Chemical Building Block: Utilized in multi-step organic synthesis for introducing chlorophenyl and epoxide functionalities with precise stereocontrol.
• Flavor & Fragrance Industry: Potential intermediate for the synthesis of complex chiral aroma chemicals.
