tert-Butylphenyl diphenyl phosphate (Cat No.: R024475) is an organophosphorus compound featuring a phosphate ester core bonded to two phenyl groups and one tert-butyl-substituted phenyl group. It is commonly used as a flame retardant additive in polymers, resins, and coatings, offering thermal stability and chemical resistance. Its bulky tert-butyl group enhances compatibility with hydrophobic polymer matrices. Additionally, it may serve as an intermediate in chemical synthesis or materials research where controlled flame retardancy and plasticizing effects are desired in high-performance applications.
