Description

cis-(3-Methyloxiranyl)Phosphonic Acid Bis(Phenylmethyl) Ester is a specialized organophosphorus compound featuring a reactive oxirane (epoxide) ring, making it a valuable bifunctional intermediate. Its molecular structure allows it to act as a key building block in the synthesis of advanced materials and fine chemicals, offering opportunities for cross-linking and polymer modification. This high-purity intermediate is primarily sought by R&D chemists and process engineers in the pharmaceutical, agrochemical, and specialty polymer industries for developing novel active ingredients and functional additives.

Application

• Pharmaceutical Intermediate: Serves as a key precursor in the synthesis of novel drug candidates, particularly those targeting bone-related disorders or requiring phosphonate functional groups for bioactivity.
• Agrochemical Synthesis: Used in the research and development of new herbicides, plant growth regulators, or insecticides where the phosphonic ester and epoxide moieties impart specific biological activity.
• Polymer Modification & Cross-linking Agent: The reactive epoxide ring enables its use as a cross-linker or co-monomer in specialty resins, coatings, and adhesives to enhance thermal stability, adhesion, or chemical resistance.
• Ligand & Catalyst Development: Acts as a starting material for creating novel chiral or bidentate phosphonate ligands used in asymmetric catalysis and metal complexation.
• Surface Treatment Agent: Potential application in formulating surface modifiers or coupling agents for glass, metals, or composites to improve interfacial bonding.
• Flame Retardant Synthon: Can be incorporated as a reactive component in the synthesis of organophosphorus flame retardants for polymers and textiles.

Quality Control

Every batch of cis-(3-Methyloxiranyl)Phosphonic Acid Bis(Phenylmethyl) Ester is manufactured and tested under strict quality management systems. We ensure compliance with relevant industry standards for fine chemical intermediates. Comprehensive analytical testing, including HPLC, GC, NMR, and IR spectroscopy, is performed to verify identity, purity, and consistency. A detailed Certificate of Analysis (COA) documenting all specifications is provided with each shipment and is available upon request.

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 hygroscopic nature, the container must be kept tightly sealed to exclude moisture. Keep away from heat, sparks, and open flame. For long-term storage, consider using an inert atmosphere to maintain product integrity.
