N,N-diethyl-m-toluamide

N,N-diethyl-m-toluamide is a monocarboxylic acid amide resulting from the formal condensation of the carboxy group of m-toluic acid with the nitrogen of diethylamine. First developed by the U.S. Army in 1946 for use by military personnel in insect-infested areas, it is the most widely used insect repellent worldwide. It has a role as a xenobiotic, an insect repellent and an environmental contaminant. It is a member of benzamides and a monocarboxylic acid amide. It is functionally related to a m-toluic acid.
