Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of nicotinic acid derivatives with biological activity. It serves as a building block in the production of antihypertensive agents and other cardiovascular drugs. The aldehyde and ester functional groups allow for versatile chemical modifications, enabling the formation of complex heterocyclic structures. Commonly employed in research settings for the preparation of pyridine-based compounds with potential therapeutic applications. Also utilized in the design of kinase inhibitors and other enzyme-targeted drug candidates.
