Description

Oxirane, (4-Methoxyphenyl)-, (2S)- (9Ci) is a chiral epoxide building block of significant interest in fine chemical synthesis. Its defined stereochemistry and reactive oxirane ring make it a valuable precursor for creating enantiomerically pure compounds. This intermediate is primarily sought after by research institutions and manufacturers in the pharmaceutical and agrochemical sectors for developing active ingredients and advanced materials.

Application

• Pharmaceutical Intermediate: Key chiral synthon for the synthesis of enantiomerically pure drug candidates and active pharmaceutical ingredients (APIs).
• Agrochemical Synthesis: Used in the production of chiral herbicides, fungicides, and plant growth regulators requiring specific stereochemistry.
• Liquid Crystal & Advanced Material Precursor: Serves as a building block for chiral dopants and monomers used in liquid crystal displays (LCDs) and specialty polymers.
• Asymmetric Catalysis Research: Employed as a standard substrate or ligand precursor in the development and testing of new asymmetric catalytic processes.
• Flavor & Fragrance Ingredient Synthesis: Utilized in the multi-step synthesis of complex, high-value chiral aroma chemicals.
