N,N-Diethyl-3-methylbenzamide 99%TC CAS 134-62-3 DEET

DEET (chemical name N,N-diethyl-meta-toluamide) is used as the active ingredient in many insect repellents. Insect repellents that contain DEET offer the best protection against mosquito bites. DEET is designed for direct application to skin to repel insects, rather than kill them. Products containing DEET currently are available to the public in a variety of liquids, lotions, sprays, and impregnated materials (e.g., wrist bands). Concentrations of DEET in products that are designed for application to skin range from 4% to 100%.

DEET is a clear or 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.
