Isomalathion is an impurity found in some batches of malathion. Whereas the structure of malation is, generically, RSP(S)(OCH 3) 2, the connectivity of isomalathion is RSPO(SCH 3)(OCH 3). It arises by heating malathion. Being significantly more toxic to humans than malathion, it has resulted in human poisonings. [1]
The former is a precursor to malathion. In the Michalski reaction , a thiophosphate reacts with chlorine gas to give a diorganylphosphorylsulfenyl chloride: [ 5 ] (RO) 3 PS + Cl 2 → (RO) 2 P(O)SCl + RCl
Parathion, also called parathion-ethyl or diethyl parathion, is an organophosphate insecticide and acaricide.It was originally developed by IG Farben in the 1940s. It is highly toxic to non-target organisms, including humans, so its use has been banned or restricted in most countries.
