Description

2-Chlorophenyl Phosphorodichloridate is a key organophosphorus intermediate characterized by its reactive dichloridate group. This compound is essential for the synthesis of more complex molecules, particularly in the development of agrochemicals and pharmaceuticals, where it serves as a versatile building block. It is primarily sought by R&D chemists and process development teams in the fine chemical, crop protection, and active pharmaceutical ingredient (API) manufacturing sectors.

Application

• Agrochemical Intermediate: A critical precursor in the synthesis of organophosphate insecticides and herbicides.
• Pharmaceutical Synthesis: Used as a phosphorylating agent in the production of nucleotide analogs and other bioactive molecules.
• Chemical Research & Development: Serves as a versatile reagent for introducing the 2-chlorophenyl phosphate moiety in novel compound libraries.
• Polymer Chemistry: Can be employed as a monomer or modifier in the synthesis of specialty phosphorous-containing polymers.
• Ligand and Catalyst Preparation: Useful for synthesizing phosphite and phosphate ligands used in homogeneous catalysis.
• Flame Retardant Synthon: Acts as a building block for developing phosphorus-based flame retardant additives.

Quality Control

Every batch of 2-Chlorophenyl Phosphorodichloridate is manufactured and tested under strict quality management systems. Our products undergo rigorous quality testing to ensure compliance with industry standards. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are available upon request.

Storage

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