Description

Oxirane, [4-(1-Methylethyl)Phenyl]-, (2S)- (9Ci) is a chiral epoxide compound of significant interest in advanced organic synthesis. This high-purity intermediate matters for its role as a key building block in the production of enantiomerically pure pharmaceuticals and fine chemicals. It is primarily needed by R&D laboratories and production facilities in the pharmaceutical, agrochemical, and specialty chemical industries seeking to introduce stereochemical complexity into target molecules.

Application

• Pharmaceutical Intermediate: A critical chiral synthon for the synthesis of active pharmaceutical ingredients (APIs), particularly in routes requiring the introduction of a stereogenic center.
• Agrochemical Synthesis: Used in the development of enantiomerically pure herbicides, fungicides, and plant growth regulators where specific stereochemistry is essential for bioactivity.
• Liquid Crystal & Advanced Material Precursor: Serves as a building block for chiral dopants and other functional materials used in display technologies and optical devices.
• Asymmetric Catalysis Research: Employed as a standard substrate or reagent in academic and industrial research focused on developing new epoxidation or ring-opening catalytic methodologies.
• Fine Chemical Production: Utilized in the multi-step synthesis of complex fragrance compounds, flavors, and other high-value specialty chemicals.
