2-n-Octylbenzotriazole is a synthetic organic compound that is used as an additive in lubricants and as a preservative in cosmetics. It is also used to produce other chemicals, such as insecticides, dyes, and pharmaceuticals. 2-n-Octylbenzotriazole has been shown to be reactive with chlorine or bromine to form an intermediate addition product that can add onto a nucleophilic substrate. The reactivity of 2-n-octylbenzotriazole is temperature dependent; at higher temperatures the reactivity increases due to increased solubility and catalysis by the metal. 2-n-Octylbenzotriazole is soluble in ethyl alcohol, but insoluble in water.
