Description

Oxirane, 2-(4-Fluorophenyl)-2-Methyl-, (2R)- (9Ci) is a high-value, chiral epoxide building block of significant interest in advanced organic synthesis. Its core value proposition lies in its stereochemical purity, which is critical for directing the stereoselective outcome of ring-opening reactions to produce enantiomerically enriched intermediates. This compound is essential for research and development chemists in the pharmaceutical and agrochemical industries, where it serves as a key precursor for the synthesis of active pharmaceutical ingredients (APIs) and other complex, fluorinated molecules. The CAS number for this compound is 235096-15-8.

Application

• Pharmaceutical Intermediate: A critical chiral synthon for the synthesis of enantiomerically pure drug candidates, particularly those targeting central nervous system (CNS) disorders and other therapeutic areas requiring fluorinated motifs.
• Agrochemical Synthesis: Used in the research and production of advanced, optically active pesticides and herbicides, where the specific stereochemistry can influence biological activity and environmental profile.
• Asymmetric Catalysis Research: Serves as a standard substrate or reagent in academic and industrial laboratories for developing and testing new catalytic methodologies for epoxide ring-opening and functionalization.
• Liquid Crystal & Advanced Material Precursor: Employed in the synthesis of fluorinated aromatic components for high-performance liquid crystals and specialty polymers with tailored electronic or optical properties.
• Custom Synthesis & Contract Manufacturing: A key starting material for custom synthesis houses and CDMOs (Contract Development and Manufacturing Organizations) producing bespoke fine chemicals for client projects.

Quality Control

Every batch of Oxirane, 2-(4-Fluorophenyl)-2-Methyl-, (2R)- (9Ci) is produced and controlled under a strict quality management system. We employ advanced analytical techniques including chiral HPLC, GC, and NMR to ensure high enantiomeric excess (ee) and chemical purity, meeting the exacting standards required for pharmaceutical R&D. A comprehensive Certificate of Analysis (COA) detailing identity, purity, enantiomeric excess, and impurity profiles is provided with each shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at a controlled room temperature (15-25°C). Keep away from strong bases and incompatible materials such as oxidizing agents and strong acids. For long-term storage under an inert atmosphere (e.g., nitrogen or argon) is recommended to maintain stability.
