3-(2H-Tetrazol-5-yl)benzonitrile is a chemical compound that belongs to the class of heterocyclic compounds. It is used as a reagent in organic synthesis for the cycloaddition reaction between an azide and an alkyne to form a 1,3-dipolar adduct. The 3-(2H-Tetrazol-5-yl)benzonitrile molecule has two tautomeric forms, with the ortho and para isomers being energetically favored. The rate constants for the 1,3-dipolar cycloaddition reactions are dependent on temperature and concentrations of reactants, but not on the relative orientation of reactants or products.
