4-Methylbenzotriazole is a benzotriazole derivative used as a corrosion inhibitor. 4-Methyl-1H-benzotriazole serves as an essential component within the mixture of aircraft deicing and anti-icing fluids (ADAFs). This compound can be synthesized through a multi-step process, starting from easily obtainable materials. The critical stages of synthesis encompass the creation of the benzotriazole ring and the incorporation of the methyl group at the precise location.
