N,N-Diethyl-m-toluamide, commonly known as DEET and identified by CAS number 134-62-3, is a highly effective insect repellent widely used in personal care products. DEET's primary function is to repel biting insects, including mosquitoes, ticks, fleas, and flies, which can carry diseases like malaria, Lyme disease, and Zika virus. It works by interfering with the insects' olfactory receptors, making it difficult for them to detect human presence. Available in various concentrations, DEET is formulated into sprays, lotions, gels, and wipes, providing versatile protection in outdoor and high-risk environments. Its use extends to treating clothing and gear, enhancing the effectiveness of insect prevention. Additionally, DEET is a critical component in military and occupational settings, where preventing insect bites is essential for health and safety. Public health initiatives also utilize DEET-based products to reduce the spread of vector-borne diseases. With a proven track record of efficacy and safety when used as directed, DEET remains a trusted choice for personal and community protection against biting insects.

Function:
The primary function of N,N-Diethyl-m-toluamide (DEET) is as an insect repellent. Its main role is to prevent biting insects, such as mosquitoes, ticks, fleas, and flies, from detecting and landing on the skin of humans or animals. DEET achieves this by interfering with the insect's olfactory receptors, which are responsible for detecting the chemical cues emitted by humans, such as carbon dioxide and body odor.
By masking or confusing these signals, DEET reduces the likelihood of insects landing on the treated surface and biting, thus providing protection against insect bites and the potential transmission of insect-borne diseases. DEET is not an insecticide, meaning it does not kill insects but rather repels them, making it a safer option for use on skin and clothing. This function makes DEET an essential component in various insect repellent formulations, offering reliable protection in both recreational and occupational settings.
