Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors for targeted cancer therapies. It serves as a building block in the preparation of active pharmaceutical ingredients (APIs) due to its reactive nitrile and carbonyl functional groups, which allow for further chemical modifications. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies, especially in optimizing pyridine-based drug candidates. Also utilized in agrochemical research for designing novel pesticides with improved efficacy and selectivity.
