Description

(R)-(4-Methoxyphenyl)Oxirane is a high-purity chiral epoxide building block of significant importance in asymmetric synthesis. Its enantiomerically pure structure makes it a critical intermediate for the development of active pharmaceutical ingredients (APIs) and advanced fine chemicals. This compound is primarily needed by research institutions and manufacturers in the pharmaceutical, agrochemical, and specialty chemical industries seeking to introduce chirality into complex molecular architectures.

Application

• Pharmaceutical Intermediate: Key chiral precursor for the synthesis of enantiomerically pure drugs, particularly in cardiovascular and central nervous system (CNS) therapeutic areas.
• Agrochemical Synthesis: Used in the production of chiral pesticides and herbicides where specific stereochemistry is required for biological activity.
• Liquid Crystal & Advanced Material Production: Serves as a building block for chiral dopants and other optically active materials used in display technologies.
• Asymmetric Catalysis Research: A valuable substrate for developing and testing new chiral catalysts and synthetic methodologies in academic and industrial R&D.
• Flavor & Fragrance Industry: Intermediate for the synthesis of enantiomerically defined aroma chemicals.
• Custom Synthesis & Contract Manufacturing: Employed by CDMOs for the bespoke production of complex chiral molecules for clients.
