Description

Bis(4-Chlorophenyl) Phosphorochloridate is a key organophosphorus intermediate with a reactive phosphoryl chloride group. This compound matters for its role as a versatile building block in the synthesis of more complex phosphorus-containing molecules, enabling the introduction of the bis(4-chlorophenyl) phosphate moiety. It is needed by manufacturers in the agrochemical and pharmaceutical industries for producing pesticides, flame retardants, and specialized ligands.

Application

• Agrochemical Intermediate: A critical precursor in the synthesis of organophosphate insecticides and herbicides.
• Pharmaceutical Synthesis: Used in the development of prodrugs and active pharmaceutical ingredients (APIs) containing phosphate ester groups.
• Flame Retardant Production: Serves as a building block for creating halogenated organophosphate flame retardants for polymers and textiles.
• Ligand and Catalyst Preparation: Employed in the preparation of specialized phosphonate ligands for metal catalysis and extraction processes.
• Polymer Modification: Used to introduce flame-retardant or modifying groups into polymer chains.
• Research & Development: A valuable reagent in organic and medicinal chemistry research for constructing novel phosphorus compounds.

Quality Control

Our Bis(4-Chlorophenyl) Phosphorochloridate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including assay by titration and impurity profiling, to ensure it meets high-purity standards suitable for synthesis. Certificates of Analysis (COA) documenting identity, purity, and relevant specifications are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its moisture-sensitive (hygroscopic) nature, containers must be kept tightly sealed under an inert atmosphere such as nitrogen or argon to prevent hydrolysis. Keep away from strong acids, bases, and oxidizing agents.
