What is (E)-Methomyl?
Plain description, key identifiers and synonyms
Methomyl is a carbamate ester obtained by the formal condensation of methylcarbamic acid with the hydroxy group of 1-(methylsulfanyl)acetaldoxime. It has a role as an acaricide, an insecticide, a nematicide, an agrochemical, a xenobiotic, an EC 3.1.1.8 (cholinesterase) inhibitor, an EC 3.1.1.7 (acetylcholinesterase) inhibitor and an environmental contaminant. It is an aliphatic sulfide and a carbamate ester. It is functionally related to a 1-(methylsulfanyl)acetaldoxime and a methylcarbamic acid.
