Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and antiviral agents. Its structure supports the construction of heterocyclic compounds that are active in biological systems. Commonly employed in medicinal chemistry for modifying pyrimidine-based drug candidates to enhance binding affinity and selectivity. Also utilized in agrochemical research for designing novel pesticides with improved efficacy. The carboxylic acid and nitrile functional groups allow for versatile derivatization, making it valuable in combinatorial chemistry and library synthesis for drug discovery.
