DEET Insect Repellent

DEET Insect Repellent (N,N-Diethyl-m-toluamide) Put safety first while being outdoors. The Vertellus line of registered insect repellent products and formulations helps keep away those annoying insects and reduces your risk of insect-borne diseases. DEET is the most widely used active ingredient in consumer insect repellents worldwide. It is unparalleled when it comes to keeping mosquitoes, ticks, and other bugs away.

DEET, discovered by the US Army in the late 1940s, has long been the gold standard for repellent active ingredients. Our U.S. production facility in Greensboro, North Carolina manufactures and supplies DEET globally.

According to Jonathan F. Day, Professor of Medical Entomology, University of Florida, Florida Medical Entomology Laboratory, “DEET is one of the safest, most reliable products on the market. Researchers are constantly searching for new repellents and during the past 40 years, nothing has come close to DEET in terms of repellent efficacy against biting arthropods (insects and ticks).”

Food Colorant

2-Vinylpyridine is the key intermediate in the production of the API, betahistine, an anti-vertigo medicine.

2-Vinylpyridine is a reactive monomer and once polymerized, the nitrogen is less exposed/accessible than its counterpart, 4-Vinylpyridine. It can be copolymerized with many other monomers, in particular cationic monomers, such as acrylamide, acrylates, and also with other vinyl-based monomers (e.g. styrene). The benefit of the addition of a 6-membered heterocyclic moiety is the increased Van der Waals forces which impart better electrostatic forces to the finished polymer, improving adhesion.
