Description

Oxiranecarboxylic Acid, 3-Propyl-, Methyl Ester, (2R,3S)- (9Ci) is a high-purity, stereochemically defined epoxide derivative that serves as a critical chiral building block in advanced organic synthesis. Its precise stereochemistry and reactive oxirane ring make it an invaluable intermediate for constructing complex molecules with defined three-dimensional architecture. This compound is primarily sought after by research institutions and pharmaceutical companies engaged in the development of novel active pharmaceutical ingredients (APIs) and fine chemicals.

Application

• Pharmaceutical Intermediate: Key chiral synthon for the synthesis of complex drug candidates, particularly in oncology and central nervous system (CNS) therapeutic areas.
• Asymmetric Synthesis: Used in stereoselective reactions to introduce the propyl-oxirane moiety into target molecules, enabling access to enantiomerically pure compounds.
• Agrochemical Research: Intermediate in the development of novel, stereospecific pesticides and herbicides where biological activity is chirality-dependent.
• Liquid Crystal & Advanced Material Precursor: Building block for synthesizing chiral dopants and organic components used in display technologies and specialty polymers.
• Academic & Process Chemistry: Valuable reagent for methodological development in organic chemistry and scale-up process optimization for fine chemical production.
