O,O'-Dimethyl dithiophosphate is widely used in the agricultural industry as an intermediate in the synthesis of organophosphate pesticides. These pesticides are effective in controlling a variety of pests, including insects and mites, by inhibiting their nervous system enzymes. Additionally, it serves as a key component in the production of flotation agents for the mining industry, where it helps in the separation of metal ores from gangue by selectively binding to metal surfaces. In the petrochemical industry, it is used as an additive in lubricating oils to reduce wear and extend the service life of machinery. Its role in these processes highlights its importance in agriculture, mineral processing, and petrochemical sectors.
