Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors for cancer treatment. It plays a key role in constructing active pharmaceutical ingredients due to its reactive chloroacetamide group and pyridine scaffold, which enhance binding selectivity. Commonly employed in research settings for designing drugs targeting tyrosine kinases and other signaling proteins involved in tumor growth. Its hydrochloride salt form improves stability and solubility during synthetic processes.
