N,N-Diethyl-m-toluamide (DEET) was nominated by the National Institute of Environmental Health Sciences (NIEHS) for toxicity and carcinogenicity testing based on its high U.S. production volume and wide spread consumer use in commercial insect
The insect repellent N,N-diethyl-m-toluamide (DEET) has been reported to inhibit AChE (acetylcholinesterase) and to possess potential carcinogenic properties with excessive vascularization. In the present paper, we demonstrate that DEET specifically stimulates endothelial cells that promote angiogenesis which increases tumor growth.

This summer, you may well have used DEET-containing products to ward off mosquitoes, ticks, and other arthropod pests. The synthesis of DEET was first reported in Romanian and German journals in 1929. The U.S. Army formulated it as a repellent after World War II, and it was commercialized in 1957.
DEET or N,N-diethyl-m-methylbenzamide has been a primary component of our synthesis . DEET is a topical insect repellent that is widely used to combat mosquitoes, fleas, ticks, flies, and other biting insects in an effort to help prevent the transmission of arthropod-borne illnesses such as malaria and West Nile virus.
DEET is a chemical (N,N-diethyl-meta-toluamide) used as the active ingredient in many insect repellent products. DEET was developed by the U.S. Army in 1946 and was registered for use by the general public in 1957.

with diethylamine (from the amine hydrochloride salt) to prepare N,N-diethyl-m-toluamide (DEET). Because corrosive acidic gases are released during the reactions, a sodium hydroxide gas trap will be used to keep them out of the lab environment. [NOTE: In the Schotten-Baumann
experiment synthesized N,N-Diethyl-m-Toluamide with a 14.4% yield. The reported yield for this reaction was 97%; however, organic chemistry students typically achieve yields from 30-50%.4 The obtained yield, when compared to the reported yields, does not indicate a very efficient synthesis and purification of DEET.
N,N-Diethyl-meta-toluamide, also called DEET (/ d iː t /) or diethyltoluamide, is the most common active ingredient in insect repellents. It is a slightly yellow oil intended to be applied to the skin or to clothing and provides protection against mosquitoes, ticks, fleas, chiggers, leeches and many biting insects.

In this experiment, m-Toluic acid, 3-Methylbenzoic acid, CAS 99-04-7 was used as raw material to react with thionyl chloride to prepare m-methylbenzoyl chloride, and then Schotten-Baumann reaction was used to obtain insect repellent DEET (N,N-diethyl m-methylbenzene). The amide) had a yield of 3.1567 g and a yield of 55.0%.
