Diphenyl phosphite

Description:

Diphenyl phosphite, with the CAS number 4712-55-4, is an organophosphorus compound characterized by its chemical formula C12H13O4P. It appears as a colorless to pale yellow liquid and is known for its role as a phosphite ester. This compound is primarily used as an antioxidant and stabilizer in various polymer applications, particularly in plastics and rubber, to prevent degradation from heat and light exposure. Diphenyl phosphite exhibits moderate toxicity and should be handled with care, as it can cause irritation to the skin, eyes, and respiratory system upon exposure. It has a relatively low volatility, which contributes to its stability in formulations. Additionally, diphenyl phosphite can participate in chemical reactions, such as transesterification, making it useful in synthetic organic chemistry. Its properties, including solubility in organic solvents and reactivity with certain nucleophiles, make it a valuable compound in both industrial and research settings. Proper safety measures should be observed when working with this substance to mitigate any potential health risks.
