Description

Chlorophosphorane CAS NO 24567-53-1 is a highly reactive organophosphorus compound primarily used as a key intermediate in advanced chemical synthesis. Its value lies in its ability to act as a versatile phosphorylating and chlorinating agent, facilitating the creation of complex molecules. This product is essential for research and development laboratories, pharmaceutical manufacturers, and agrochemical producers involved in creating novel active ingredients and fine chemicals.

Application

• Pharmaceutical Intermediate: Critical for the synthesis of nucleotide analogs, prodrugs, and other active pharmaceutical ingredients (APIs).
• Agrochemical Synthesis: Used in the production of organophosphate insecticides, herbicides, and plant growth regulators.
• Ligand and Catalyst Preparation: Serves as a precursor for phosphine ligands and metal-complex catalysts used in asymmetric synthesis.
• Flame Retardant Production: An intermediate in the manufacture of specialized organophosphorus flame retardants for polymers and textiles.
• Chemical Research: Employed in academic and industrial R&D for constructing P-C, P-N, and P-O bonds in novel compounds.
• Polymer Modification: Used to introduce phosphorus-containing functional groups into polymer chains to alter material properties.

Quality Control

Our Chlorophosphorane is manufactured under strict quality management systems. Every batch undergoes comprehensive analytical testing to ensure high purity and consistency, meeting the stringent requirements of industrial and research applications. A detailed Certificate of Analysis (COA) is provided with each shipment, documenting key parameters such as assay, identity, and impurity profiles.

Storage

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