General description

4-Pyridinecarboxaldehyde is a heterocyclic building block used to prepare Schiff bases via a Korich-type reaction.

Application

4-Pyridinecarboxaldehyde can be used for the synthesis of:
  • ʅ,β-Unsaturated amides by coupling with N,N-disubstituted formamides.
  • meso-Substituted A3-corroles.
  • N-(4-pyridylmethyl)-L-valine as a ligand to construct zinc metal–organic frameworks (Zn-MOFs).
  • 4′-Pyridyl terpyridines, with potential application as anticancer and antimicrobial agents.
  • 4-pyridinecarboxaldehyde thiosemicarbazone, as a corrosion inhibitor for mild steel.
