Used in pharmaceutical research as a building block for synthesizing biologically active compounds. Its structure supports the development of drugs targeting neurological disorders and infectious diseases due to the presence of nitrogen-containing heterocycles that enhance binding to biological targets. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies, particularly in optimizing potency and selectivity of new drug candidates. Also utilized in the preparation of kinase inhibitors and receptor modulators. Its water solubility, especially in salt form, improves bioavailability in preclinical formulations.
