Description

(R)-2-((4-Bromophenoxy)Methyl)Oxirane is a high-purity chiral epoxide building block of significant interest in advanced organic synthesis. This compound matters because its stereochemistry and reactive oxirane ring make it a critical precursor for constructing complex, optically active molecules with high enantiomeric purity. Pharmaceutical R&D and fine chemical manufacturers need it for the development of active pharmaceutical ingredients (APIs), agrochemicals, and specialty materials where precise molecular configuration is essential.

Application

• Pharmaceutical Intermediate: A key chiral synthon for the synthesis of enantiomerically pure APIs, particularly in neurological and cardiovascular drug research.
• Agrochemical Synthesis: Used in the production of advanced, stereospecific herbicides, fungicides, and plant growth regulators.
• Liquid Crystal & OLED Materials: Serves as a building block for chiral dopants and advanced electronic materials requiring specific optical properties.
• Asymmetric Catalysis Research: Employed as a substrate or ligand precursor in the development of new catalytic systems.
• Polymer Modification: Utilized to introduce chiral centers or reactive sites into specialty polymer chains for advanced material science.
• Custom Synthesis & Contract Manufacturing: A valuable starting material for custom synthesis projects requiring high enantiomeric excess (ee).
