Description

Oxirane, 2-(4-Fluorophenyl)-2-Methyl-, (2S)- (9Ci) is a high-value, chiral epoxide building block of significant interest in advanced organic synthesis. Its core value lies in the precise stereochemistry and reactive oxirane ring, which enables the controlled introduction of a fluorinated phenyl moiety into complex molecular architectures. This compound is essential for research and development chemists in the pharmaceutical and agrochemical industries, particularly for constructing active pharmaceutical ingredients (APIs) and other fine chemicals where the (S)-configuration and fluorine substitution are critical for biological activity.

Application

• Pharmaceutical Intermediate: A key chiral synthon for the synthesis of novel drug candidates, especially in central nervous system (CNS) and anti-inflammatory therapeutic areas.
• Agrochemical Synthesis: Used in the development of advanced pesticides and herbicides, where the fluorophenyl group enhances bioavailability and stability.
• Asymmetric Catalysis Research: Serves as a standard substrate or building block for developing and testing new chiral catalysts and synthetic methodologies.
• Liquid Crystal & Advanced Material Precursor: Employed in the synthesis of fluorinated organic compounds for electronic and optical materials.
• Custom Chemical Synthesis: Provides a versatile starting point for contract research organizations (CROs) and fine chemical manufacturers producing bespoke compounds for clients.

Quality Control

Every batch of Oxirane, 2-(4-Fluorophenyl)-2-Methyl-, (2S)- is produced under strict quality management systems. We employ advanced analytical techniques, including chiral HPLC, GC, and NMR, to ensure high enantiomeric excess (ee) and chemical purity suitable for demanding synthetic applications. A comprehensive Certificate of Analysis (COA) detailing identity, purity, chiral purity, and impurity profiles is provided with each shipment to guarantee traceability and batch-to-batch consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (typically 15-25°C). The compound may be sensitive to moisture and strong acids/bases; keep the container tightly sealed under an inert atmosphere for long-term storage.
