Description

Oxiranecarboxylic Acid, 3-Methyl-, Butyl Ester, (2S,3R)- (9Ci) is a high-purity, stereochemically defined glycidyl ester derivative, serving as a critical chiral building block and reactive intermediate in advanced organic synthesis. Its value lies in the precise control it offers for introducing functionalized oxirane rings, enabling the synthesis of complex molecules with defined stereochemistry. This compound is essential for research and development chemists in the pharmaceutical, agrochemical, and specialty materials sectors who require enantiomerically pure intermediates for creating active ingredients and functional polymers.

Application

• Pharmaceutical Intermediate: Key chiral synthon for the production of enantiomerically pure active pharmaceutical ingredients (APIs), particularly in protease inhibitor and cardiovascular drug research.
• Agrochemical Synthesis: Used in the manufacture of advanced, stereoselective herbicides, fungicides, and plant growth regulators.
• Polymer & Resin Modification: Acts as a reactive monomer or cross-linking agent for epoxy resins and specialty polymers, imparting tailored mechanical and chemical resistance properties.
• Fine Chemical Production: Serves as a versatile intermediate for synthesizing complex natural products, flavors, and fragrances where stereochemical integrity is paramount.
• Liquid Crystal & OLED Materials: A potential precursor in the development of chiral dopants and electron-transport materials for display and lighting technologies.
• Cross-coupling Reactions: Utilized in palladium-catalyzed and other metal-mediated coupling reactions to construct complex molecular architectures.
