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 amine functionality and pyridine core, which enhance binding selectivity in drug molecules. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies. Also utilized in the production of agrochemicals and functional materials where nitrogen-containing heterocycles are required. Its hydrochloride salt form improves stability and solubility in aqueous and polar organic solvents, facilitating handling in multi-step syntheses.
