Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the production of vitamin B3 (niacin) and related nicotinamide derivatives. It serves as a building block in the preparation of pyridine-based drugs and agrochemicals due to its reactive ester groups, which allow for easy functionalization. Commonly employed in research and industrial settings for heterocyclic compound development, especially in medicinal chemistry for designing enzyme inhibitors and bioactive molecules.
