Used in the synthesis of nicotinamide adenine dinucleotide (NAD) analogs and pharmaceuticals, particularly in the production of antituberculosis drugs like isoniazid. Acts as a building block in the development of pyridine-based compounds for medicinal chemistry. Employed in coordination chemistry as a ligand for metal complexes with potential catalytic or biological activity. Also utilized in the preparation of corrosion inhibitors and in the design of functional materials due to its ability to form stable hydrogen-bonded networks.
