Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of antitubercular drugs. It serves as a building block for pyridine-based compounds due to its reactive aldehyde and ester functional groups, enabling diverse chemical transformations. Commonly employed in medicinal chemistry for constructing heterocyclic systems and in the preparation of nicotinamide analogs. Also utilized in research settings for designing bioactive molecules and drug candidates targeting infectious diseases.
