Description and Uses

4-Pyridinecarboxaldehyde can be used for the synthesis of:

• ?,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.
