What is Triphenyl phosphorothionate?
Triphenyl phosphorothionate (CAS 597-82-0), also known as triphenyl phosphorothioate, is an organophosphorus ester used primarily as a synergist and stabilizer in agrochemical formulations.
Where is Triphenyl phosphorothionate used?
- Pesticide formulations: synergist that boosts performance
- Pyrethroid and organophosphate insecticides: allows reduced active ingredient loading while maintaining efficacy
- Emulsifiable concentrates and wettable powders: incorporated where oxidative degradation of the active substance is a concern
- Stored grain pests and crop protection: co-formulant
- It is compatible with a range of carrier solvents in technical-grade insecticide blends.
Good to know: Buyers should confirm purity specifications and packaging options directly with suppliers, as grades and concentrations vary across different global chemical producers.
