Diphenyl hydrogen phosphate(CAS: 838-85-7)

Diphenyl hydrogen phosphate is a white crystalline solid with the chemical formula C12H11O4P. It is a phosphate ester derived from phosphoric acid and biphenyl, characterized by its solubility in organic solvents like ethanol and methanol. Commonly used as a precursor in organic synthesis and pharmaceutical applications, it exhibits stability under normal conditions but requires careful handling due to its potential corrosive properties.

Diphenyl hydrogen phosphate is widely utilized in the pharmaceutical industry as an intermediate for drug synthesis, in industrial applications for flame retardants and polymer additives, and in research for phosphorylation reactions. It also serves as a stabilizer in certain chemical formulations and is relevant in studies involving phosphate chemistry and organic compound development.

Diphenyl hydrogen phosphate is generally considered safe when handled properly, but it may cause skin and eye irritation due to its corrosive nature. Safety standards recommend using personal protective equipment (PPE) like gloves, goggles, and lab coats during handling. It should be stored securely and kept away from incompatible materials to ensure workplace safety and environmental compliance.

Diphenyl hydrogen phosphate should be stored in a cool, dry place, sealed in airtight containers to prevent moisture exposure. It is stable under normal storage conditions but must be protected from light and heat. Maintain a well-ventilated area and avoid contact with strong bases or oxidizing agents to ensure long-term preservation and safety.
