Diethyltoluamide(DEET), MF: C₁₂H₁₇NO, MW: 191.27, is a classic synthetic broad-spectrum insect repellent widely used in mosquito repellents. It is the most commonly used and most reliable active ingredient for repelling mosquitoes worldwide. It has no direct insecticidal effect but repels insects solely by interfering with their olfactory receptors.
