Description

2,3-Diphenyl-Oxirane (CAS NO 40102-60-1) is a high-value epoxide derivative characterized by its two phenyl substituents, making it a versatile chiral building block in advanced organic synthesis. Its rigid oxirane ring and aromatic groups are critical for constructing complex molecular architectures with specific stereochemistry. This compound is essential for R&D and production chemists in the pharmaceutical, agrochemical, and specialty materials industries seeking to introduce epoxide functionality into target molecules.

Application

• Pharmaceutical Intermediate: A key chiral synthon for the development of active pharmaceutical ingredients (APIs), particularly in stereoselective synthesis.
• Agrochemical Synthesis: Used in the research and manufacture of advanced pesticides and herbicides, where the epoxide moiety acts as a reactive handle.
• Polymer & Resin Modifier: Serves as a cross-linking agent or monomer in the production of specialty epoxy resins and polymers with enhanced thermal or mechanical properties.
• Ligand & Catalyst Preparation: Utilized as a precursor for synthesizing chiral ligands and catalysts used in asymmetric catalysis.
• Fine Chemical Production: Employed in the multistep synthesis of dyes, flavors, fragrances, and other high-value fine chemicals.
• Academic & Industrial Research: A valuable tool in methodological development and exploratory chemistry for novel reaction pathways.

Quality Control

Our 2,3-Diphenyl-Oxirane is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including chromatography (HPLC/GC) and spectroscopic methods (NMR, IR), to ensure high chemical purity and consistent isomeric composition. A detailed Certificate of Analysis (COA) documenting identity, purity, and impurity profiles is provided with every shipment to support your quality assurance protocols.

Storage

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