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.

It functions by enhancing the efficacy of active ingredients and improving the oxidative stability of formulated products. In pesticide formulations, it acts as a synergist to boost performance.

This additive is particularly effective with pyrethroid and organophosphate insecticides, allowing formulators to reduce active ingredient loading while maintaining high levels of efficacy.

It is incorporated into emulsifiable concentrates and wettable powder formulations where oxidative degradation of the active substance is a concern for long-term storage and use.

Agricultural chemical manufacturers also use it as a co-formulant in products targeting stored grain pests and crop protection applications across various global markets.

Its compatibility with a range of carrier solvents makes it a practical additive in technical-grade insecticide blends destined for both professional and agricultural sectors.

Triphenyl phosphorothionate is supplied as a liquid or low-melting solid, typically available in technical grade. It is commonly offered in drum and IBC quantities for manufacturing.

Buyers should confirm purity specifications and packaging options directly with suppliers, as grades and concentrations vary across different global chemical producers.
