Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and other bioactive molecules. Its structure supports the formation of nitrogen-rich heterocyclic compounds, which are common in drug design for oncology and central nervous system disorders. It is also employed in research settings for building novel pyrazole-fused scaffolds with potential anti-inflammatory and antiviral properties. The hydrochloride salt form enhances solubility and stability, making it suitable for solution-phase reactions in medicinal chemistry.
