PRODUCT INTRODUCTION
description
Mecarbam is an organic thiophosphate that is O,O-diethyl hydrogen phosphorodithioate in which the hydrogen attached to a sulfur is replaced by a 2-[(ethoxycarbonyl)(methyl)amino]-2-oxoethyl group. It has a role as an EC 3.1.1.7 (acetylcholinesterase) inhibitor, an acaricide and an agrochemical. It is an organic thiophosphate, an organothiophosphate insecticide and a carbamate ester.
