Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and other bioactive molecules. Its structure supports binding to enzyme active sites, making it valuable in drug discovery for cancer and inflammatory diseases. Also employed in research for designing novel heterocyclic compounds with potential antimicrobial or antiviral activity. The hydrochloride salt form enhances solubility and stability, facilitating its use in biological assays and formulation studies.
