Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of nicotinamide-based drugs and kinase inhibitors. Its aldehyde and ester functional groups allow for versatile chemical modifications, enabling the construction of complex heterocyclic systems. Commonly employed in medicinal chemistry for structure-activity relationship studies and in the preparation of biologically active molecules targeting inflammation, cancer, and central nervous system disorders. Also utilized in agrochemical research for designing novel pesticides and herbicides due to its ability to enhance molecular binding and selectivity.
