Diethyl P-[[3,5-bis(1,1-dimethylethyl)-4-hydroxyphenyl]methyl]phosphonate

Description:

Diethyl P-[[3,5-bis(1,1-dimethylethyl)-4-hydroxyphenyl]methyl]phosphonate, with CAS number 976-56-7, is an organophosphorus compound characterized by its phosphonate functional group. This substance typically appears as a colorless to pale yellow liquid and is known for its applications as a flame retardant and antioxidant in various materials, particularly in plastics. The presence of the bulky tert-butyl groups enhances its thermal stability and reduces volatility, making it effective in high-temperature applications. The hydroxyphenyl moiety contributes to its antioxidant properties, allowing it to scavenge free radicals and inhibit oxidative degradation. Additionally, the diethyl ester groups provide solubility in organic solvents, facilitating its incorporation into different formulations. Safety data indicate that, like many organophosphorus compounds, it should be handled with care due to potential toxicity, and appropriate safety measures should be observed during its use. Overall, this compound exemplifies the utility of phosphonates in enhancing the performance and longevity of materials in various industrial applications.
