Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the production of nicotinic acid derivatives and pyridine-based drugs. Its aldehyde and ester functional groups allow for versatile chemical transformations, making it valuable in creating active pharmaceutical ingredients (APIs). Commonly employed in condensation reactions and cyclization processes to build complex heterocyclic systems. Also utilized in agrochemical synthesis for developing novel pesticides and herbicides. Its reactivity supports use in research laboratories for designing new organic compounds with potential biological activity.
