Organophosphate
Organophosphates (also known as phosphate esters) are a class of organophosphorus compounds with the general structure O=P(OR). They can be considered as esters of phosphoric acid. Like most functional groups organophosphates occur in a diverse range of forms, with important examples including key biomolecules such as DNA, RNA and ATP, as well as many insecticides, herbicides, and nerve agents.
Carbophenothion
Carbophenothion is a highly toxic organophosphate insecticide and acaricide. Organophosphates are acetylcholinesterase inhibitors and disrupt the signal transduction at the cholinergic synapse. It is classified as Restricted Use Pesticide (RUP) by the Environmental Protection Agency (EPA). Carbophenothion is used in different brands like Trithion. This pesticide contains 80% carbophenothion as its only active ingredient. Because of the widespread use of those organophosphates in the nineties in the US, it was the most common cause of agricultural poisonings.
