Used as a key intermediate in the synthesis of fluorinated pharmaceuticals, particularly in the production of kinase inhibitors and antiviral agents. Its aldehyde and nitrile functional groups allow for selective reactions, enabling the construction of complex heterocyclic structures. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies due to the electron-withdrawing effects of fluorine atoms enhancing metabolic stability and bioavailability. Also utilized in the development of agrochemicals, where fluorine substitution improves lipophilicity and target binding affinity.
