Uses

Used in Pesticide Synthesis:
POTASSIUM DI-ISO-PROPYLDITHIOPHOSPHATE is used as an intermediate in the synthesis of Isodimethoate, which is an isomer of Dimethoate (D460505). This organophosphate insecticide is anticholinesterase, meaning it disables cholinesterase, an enzyme essential for central nervous system function. As a result, it exhibits neurotoxic effects on humans.
Used in Insecticide Formulations:
POTASSIUM DI-ISO-PROPYLDITHIOPHOSPHATE is used as a component in the formulation of Dimethoate, a widely used pesticide. The presence of Isodimethoate in these formulations contributes to their effectiveness in controlling pests, as it reacts with AChE in human red blood cells, making part of the enzyme non-reactivatable and enhancing the insecticide's neurotoxic properties.

Synthesis, Stability, and Kinetics of Hydrogen Sulfide Release of Dithiophosphates

The development of chemicals to slowly release hydrogen sulfide would aid the survival of plants under environmental stressors as well as increase harvest yields. We report a series of dialkyldithiophosphates and disulfidedithiophosphates that slowly degrade to release hydrogen sulfide in the presence of water. Kinetics of the degradation of these chemicals were obtained at 85 °C and room temperature, and it was shown that the identity of the alkyl or sulfide group had a large impact on the rate of hydrolysis, and the rate constant varied by more than 104×. For example, using tert-butanol as the nucleophile yielded a dithiophosphate (8) that hydrolyzed 13,750× faster than the dithiophosphate synthesized from n-butanol (1), indicating that the rate of hydrolysis is structure-dependent. The rates of hydrolysis at 85 °C varied from a low value of 6.9 × 10-4 h-1 to a high value of 14.1 h-1. Hydrogen sulfide release in water was also quantified using a hydrogen sulfide-sensitive electrode. Corn was grown on an industrial scale and dosed with dibutyldithiophosphate to show that these dithiophosphates have potential applications in agriculture. At a loading of 2 kg per acre, a 6.4% increase in the harvest yield of corn was observed.

Phosphorus-31, Cadmium-113 and Mercury-199 N.M.R. Studies on Dithiolate Complexes of Cadmium and Mercury and Their Phosphine Adducts

Phosphorus-31, cadmium-113 and mercury-199 n.m.r. spectra have been recorded for a series of O,O-dialkyldithiophosphate (dtp) and dialkyldithiocarbamate (dtc) complexes of cadmium and mercury in dichloromethane solution.Both types of ligand are labile on the n.m.r. time scale at room temperature, although the exchange of dtc ligands can be slowed at low temperatures.The complexes interact with tributylphosphine and tricyclohexylphosphine (pcy), but at room temperature the phosphines are also labile.At low temperatures, however, the phosphine exchange becomes slow on the n.m.r. time scale to allow identification of the adducts except for Cd(dtc)2 adducts with PBu3 which are still labile at -110 deg C.All the data indicate that cadmium has a lower affinity for phosphine than mercury and that dtc ligands are more strongly bound to the metals than dtp ligands.
