By the dermal route, methyl parathion is much less toxic than parathion, with an LD(50) of 67 mg/kg in rats of both sexes (Hayes /Ex. 1. Parathion methyl, or methyl parathion, is an organophosphate insecticide, possessing an organothiophosphate group. It is structurally very similar to parathion-ethyl. It is not allowed for sale and import in nearly all countries around the world, while a few allow it under subject to specified conditions only. 4 Classifications and al formula: (CH₃O)₂P(S)OC₆H₄NO₂.

Parathion, also called parathion-ethyl or diethyl parathion and locally [clarification needed] known as "Folidol", is an organophosphate insecticide and was originally developed by IG Farben in the s. It is highly toxic to non-target organisms, including humans, so its use has been banned or restricted in most ance: White crystals (pure form). Parathion is a deep brown to yellow liquid with a faint odor of garlic. It is an organic phosphate insecticide which acts as an inhibitor of cholinesterase, and as such it is highly toxic by all routes of exposure. It may be found as a liquid or as a dry mixture where the liquid is absorbed onto a dry carrier.

This means that EPA believes that water containing 4-nitrophenol at or below this level is acceptable for drinking every day over the course of one's lifetime, and does.

Methyl parathion is a white crystalline solid which is often dissolved in a liquid solvent carrier. The commercial product is a tan liquid (xylene solution) with a pungent odor.
