Triphenyl phosphorothioate

Triphenyl Phosphorothioate (CAS 597-82-0, EC 209-909-9) is an organophosphorus compound carrying the molecular formula C18H15O3PS. It is also referenced under the designations T 309, Triphenyl Thiophosphate, and NSC 57867. No E-code applies to this substance.

In agrochemical formulation, Triphenyl Phosphorothioate functions as a synergist and chemical intermediate, enhancing the efficacy of active pesticidal compounds by inhibiting metabolic detoxification pathways in target organisms. It is also investigated as a plasticiser and flame-retardant additive in polymer systems, where the phosphorothioate group contributes thermal stabilisation through phosphorus-based radical quenching mechanisms.

This material is supplied as a solid grade compliant with REACH registration requirements for the European market. Standard packaging formats follow conventional industrial chemical protocols for solid organophosphorus compounds. Procurement teams should confirm current regulatory status and import documentation requirements prior to ordering.
