Description

Chlorophosphonitrile CAS NO 1832-07-1 is a reactive organophosphorus compound characterized by its unique cyclic trimeric structure. This chemical serves as a versatile intermediate in advanced synthesis, valued for its ability to introduce phosphorus-nitrogen functionalities into target molecules. It is primarily sought by R&D chemists and process engineers in the pharmaceutical, agrochemical, and specialty polymer industries for developing novel active ingredients and flame-retardant materials.

Application

• Pharmaceutical Intermediate: Key building block for synthesizing novel drug candidates, particularly those targeting neurological or metabolic pathways.
• Agrochemical Synthesis: Used in the production of advanced herbicides, insecticides, and plant growth regulators.
• Flame Retardant Precursor: Serves as a critical monomer for creating high-performance, halogen-free flame retardant additives for plastics and textiles.
• Ligand and Catalyst Development: Employed in organometallic chemistry to create novel phosphazene-based ligands for catalysis.
• Specialty Polymer Research: Acts as a monomer for developing polyphosphazenes, a class of polymers with applications in elastomers, membranes, and biomedical devices.
• Chemical Vapor Deposition (CVD): Potential use as a precursor for depositing thin films containing phosphorus and nitrogen for semiconductor or coating applications.

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 bases and oxidizing agents. Due to its reactivity with moisture and sensitivity to hydrolysis, containers should be kept sealed under an inert atmosphere (e.g., nitrogen or argon) when not in use. Recommended long-term storage temperature is 2-8°C. Allow the container to reach ambient temperature before opening to prevent moisture condensation.
