tert-Butylphenyl diphenyl phosphate - Technical grade

CAS: 56803-37-3

tert-Butylphenyl diphenyl phosphate (tBPDP) is an organophosphorus compound that has been used as a flame retardant additive in plastics and textiles. tBPDP has been detected at median concentrations of 0.2 ng/g in human urine, suggesting that it may be present in the general population. A recent transcriptomic study revealed that tBPDP inhibits the transcriptional activity of polymerase chain reaction (PCR) by binding to the DNA polymerase enzyme. It also binds to the liver microsomes of rats, demonstrating its toxicological properties. Tert-butylphenyl diphenyl phosphate is structurally related to other phosphates such as carbon disulphide, which has been studied extensively for its carcinogenic effects on humans and animals.
