Triphenyl phosphate (TPP) is an organophosphate compound composed of three phenyl groups attached to a phosphate backbone. It is widely used as a flame retardant, plasticizer, and additive in various products, including plastics, resins, and textiles. TPP functions by forming a protective layer that inhibits the spread of flames. Despite its effectiveness, there are concerns about its environmental persistence and potential health impacts. Ongoing research aims to develop safer alternatives to triphenyl phosphate for fire safety applications.
