Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors for cancer treatment. It serves as a building block in the preparation of active pharmaceutical ingredients (APIs) due to its reactive ketone group and electron-rich pyridine ring, which facilitate further chemical modifications. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies to optimize drug potency and selectivity. Also utilized in the creation of agrochemicals and functional materials where substituted pyridines enhance stability and bioactivity.
