Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of nicotinic acid derivatives with biological activity. Commonly employed in the preparation of kinase inhibitors and other nitrogen-containing heterocyclic compounds for medicinal research. Also utilized in agrochemical formulations for the creation of plant growth regulators and crop protection agents. Its aldehyde and ester functional groups allow for versatile chemical modifications, making it valuable in organic synthesis and drug discovery processes.
