Description

Oxirane, 2-(1-Cyclohexen-1-Yl)-3-(1-methylethyl)-, (2S,3R)- (9Ci) is a high-value, stereochemically defined oxirane derivative, also known as a chiral epoxide, which serves as a critical chiral building block in advanced organic synthesis. Its defined stereochemistry at the 2- and 3-positions makes it an indispensable precursor for the enantioselective construction of complex molecules, ensuring high optical purity in the final products. This compound is primarily sought by research and development laboratories and production facilities in the pharmaceutical and fine chemical industries for the synthesis of active pharmaceutical ingredients (APIs), agrochemicals, and specialty materials.

Application

• Chiral Intermediate in Pharmaceutical Synthesis: A key starting material for the enantioselective synthesis of complex drug molecules and active pharmaceutical ingredients (APIs).
• Agrochemical Precursor: Used in the research and production of chiral herbicides, fungicides, and pesticides where specific stereochemistry impacts biological activity.
• Fine Chemical Building Block: Employed in academic and industrial R&D for constructing novel, stereochemically complex organic compounds and natural product analogs.
• Ligand and Catalyst Development: Serves as a substrate or precursor in the development and testing of new asymmetric catalysts and chiral ligands.
• Material Science Research: Potential monomer or cross-linking agent in the development of polymers with specific chiral or structural properties.

Quality Control

Every batch of our chiral epoxide intermediates is produced and tested under strict quality management protocols to ensure exceptional enantiomeric purity and chemical integrity, critical for sensitive asymmetric synthesis. We provide comprehensive Certificates of Analysis (COA) detailing identity, purity (by GC/HPLC), enantiomeric excess (by Chiral HPLC), and impurity profiles. Our quality systems are designed to support cGMP and ISO standards for traceability and reproducibility, meeting the stringent requirements of pharmaceutical development.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its highly volatile nature, ensure containers are securely sealed and stored upright. Keep away from heat, sparks, open flames, and oxidizing agents.
