Isonicotinamide serves as a key precursor in synthesizing isoniazid derivatives for tuberculosis research. Its amide functionality enables coordination with metal ions to form luminescent MOFs (metal-organic frameworks). Researchers utilize it as a hydrogen-bonding scaffold in crystal engineering and supramolecular chemistry studies.
