Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors for cancer treatment. It serves as a building block in creating active pharmaceutical ingredients (APIs) due to its reactive amine functionality and pyridine ring, which enhance binding to biological targets. Commonly employed in research settings for drug discovery programs focusing on oncology and inflammatory diseases. Its hydrochloride salt form improves solubility and stability, making it suitable for use in aqueous reaction conditions.
