Phosphorous acid, tris(2-methylphenyl) ester

Description:

Phosphorous acid, tris(2-methylphenyl) ester, also known as tris(2-methylphenyl) phosphate, is an organophosphorus compound characterized by its phosphate ester structure. It typically appears as a colorless to pale yellow liquid with a high boiling point and low volatility. This compound is known for its role as a flame retardant and plasticizer in various applications, particularly in polymers and resins. It exhibits good thermal stability and is soluble in organic solvents, making it suitable for use in formulations requiring enhanced fire resistance. Additionally, tris(2-methylphenyl) phosphate has a relatively low toxicity profile compared to other phosphates, although it should still be handled with care due to potential environmental and health impacts. Its chemical properties include the ability to undergo hydrolysis, which can lead to the formation of phosphorous acid and corresponding phenols under certain conditions. Overall, this compound is valued in industrial applications for its functional properties while necessitating appropriate safety measures during handling and use.
