Application

Isonicotinic acid (IN) can be used as:
  • An organocatalyst in the one pot four component condensation reaction, to synthesize pyranopyrazoles based heterocyclic compounds.
  • An organic ligand for the preparation of copper(I) halide coordination polymer [CuBr(IN)]n, by hydrothermal method.
  • As a starting material for the synthesis of cation-dimers with potent antimalarial activity.
