Description

Diallyl Phenylphosphonate is an organophosphorus compound featuring both allyl and phenyl groups attached to a phosphonate core. This unique structure makes it a valuable reactive intermediate and monomer for advanced polymer synthesis, particularly in the development of flame-retardant and specialty polymeric materials. It is primarily sought by R&D chemists and production engineers in the polymer, resin, and specialty chemical manufacturing sectors for creating materials with enhanced thermal stability and specific functional properties.

Application

• Flame Retardant Monomer: A key building block for synthesizing phosphorus-containing polymers and copolymers with inherent flame-retardant properties for textiles, electronics, and construction materials.
• Reactive Diluent & Crosslinker: Used in specialty resin formulations, including epoxy and unsaturated polyester resins, to modify viscosity and enhance crosslinking density for improved mechanical and thermal performance.
• Polymer Modification Agent: Employed to introduce phosphonate functional groups into polymer backbones, altering properties like adhesion, thermal stability, and compatibility with other materials.
• Chemical Intermediate: Serves as a versatile precursor in organic synthesis for pharmaceuticals, agrochemicals, and ligand preparation due to its reactive allyl groups.
• Adhesive & Sealant Formulations: Incorporated to improve the heat resistance and durability of high-performance adhesives and sealants.
• Research & Development: Utilized in academic and industrial labs for developing new polymeric materials with tailored functional characteristics.

Quality Control

Our Diallyl Phenylphosphonate is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing, including assay (by GC/HPLC), identity confirmation (IR, NMR), and impurity profiling, to ensure it meets precise specifications for purity and performance. A detailed Certificate of Analysis (COA) is provided with each shipment, documenting all critical quality parameters for your verification and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials such as strong acids and oxidizing agents. Recommended storage temperature is between 15°C and 25°C. Keep container tightly sealed when not in use to prevent moisture absorption and maintain product integrity.
