Diphenyl phosphate

Description:
Diphenyl phosphate, with the CAS number 838-85-7, is an organophosphate compound characterized by its structure, which consists of two phenyl groups attached to a phosphate group. It is typically a colorless to pale yellow liquid or solid, depending on the temperature and purity. This compound is known for its role as a flame retardant and plasticizer in various applications, including polymers and coatings. Diphenyl phosphate exhibits moderate solubility in organic solvents and is relatively stable under normal conditions, although it can hydrolyze in the presence of strong acids or bases. It has a low volatility, making it suitable for use in environments where evaporation is a concern. Additionally, diphenyl phosphate is of interest in the field of environmental chemistry due to its potential effects on human health and ecosystems, prompting studies on its toxicity and biodegradability. Proper handling and disposal are essential to mitigate any environmental impact associated with its use.
