Application

1H-Benzotriazole-4-sulfonic acid can be used as:
  • A precursor for the preperation of 4-hydroxy-benzotriazole via hydrolysis using a strong alkali.[1]
  • A reactant to synthesize copper benzotriazolesulfonate phenanthroline supramolecular complex by the reaction with 1,10-phenanthroline ligand.[2]
  • A corrosion inhibitor in preparation of polystyrene nanosphere-templated cerium molybdate nanocontainers.[3]

  • Reactant for preparation of copper benzotriazolesulfonate phenanthroline supramolecular complex
  • Used as a corrosion inhibitor in preparation of polystyrene nanosphere-templated cerium molybdate nanocontainers loaded with corrosion inhibitors
