    4-Pyridinecarboxaldehyde is an heterocyclic building block used for the   synthesis of various pharmaceutical compounds, such as new   1,4-dihydropyridin-4-yl-phenoxyacetohydrazones, having anticonvulsant and   anti-inflammatory properties.4-Pyridinecarboxaldehyde and some of its   derivatives have also been reported as useful transamination reagents to   introduce ketone or aldehyde groups onto the N-termini of antibodies for   subsequent site-specifically conjugate aminooxy-functionalized molecules   (including fluorescent dyes, polyethylene glycol, or porphyrins) to these   entities.
    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.
