Diphenyl phosphonate(CAS: 4712-55-4)

Diphenyl phosphonate (CAS: 4712-55-4) is a crystalline solid with a molecular weight of approximately 194.22 g/mol. It has a low solubility in water but is more soluble in organic solvents like ethanol and acetone. Chemically, it is reactive towards nucleophiles, making it useful in various synthetic applications. Its reactivity is due to the phosphonate functionality, which can participate in nucleophilic substitution reactions.

Diphenyl phosphonate (CAS: 4712-55-4) is typically synthesized by the reaction of phosphorus oxychloride with diphenyl ketone in the presence of a base such as pyridine. The reaction involves the deprotonation of the ketone followed by the phosphonation of the resulting phenoxide ion. The yield is generally high, and the method is selective for the desired product.

Diphenyl phosphonate (CAS: 4712-55-4) is used in a variety of industries, including pharmaceuticals, where it serves as a building block for drug synthesis, and in polymers, where it is used as a stabilizer. It also finds applications in the production of sensors due to its reactivity and in semiconductor manufacturing for its role in etching processes.

When handling Diphenyl phosphonate (CAS: 4712-55-4), it is important to use personal protective equipment (PPE) such as gloves, goggles, and a lab coat. Work should be conducted in a well-ventilated area or under a fume hood to prevent inhalation. Proper spill cleanup procedures should be followed, and the product should be stored in a cool, dry place away from strong acids and bases. Always refer to the Safety Data Sheet (SDS) for detailed handling and disposal information.
