Used as a key intermediate in the synthesis of pharmaceutical agents, particularly in the development of kinase inhibitors for cancer treatment. It serves as a building block in medicinal chemistry due to its nitrogen-rich heterocyclic structure, which enhances binding affinity to biological targets. Commonly employed in the preparation of compounds targeting neurological disorders and inflammatory diseases. Its hydrochloride salt form improves solubility and stability, making it suitable for use in aqueous reaction conditions and formulation studies.
