Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of antituberculosis agents and other nitrogen-containing heterocyclic drugs. Its structure supports the formation of bioactive molecules due to the presence of both amino and carboxylic acid functional groups, enabling diverse derivatization. Commonly employed in medicinal chemistry for constructing pyridine-based scaffolds with potential antimicrobial and anti-inflammatory activity. Also utilized in the preparation of agrochemicals and specialty polymers where functionalized nicotinic derivatives enhance material properties.
