Used in pharmaceutical synthesis as a key intermediate for developing biologically active compounds, particularly in the production of kinase inhibitors and anti-inflammatory agents. Its structure supports the formation of pyrazole-based drug candidates, which are common in treatments for cancer, diabetes, and autoimmune diseases. Also employed in research settings to design novel heterocyclic compounds due to its reactive amino and carboxylic acid functional groups. The hydrochloride salt form enhances solubility and stability, making it suitable for use in aqueous reaction systems and purification processes.
