Used as an intermediate in the synthesis of biologically active compounds, particularly in the development of pharmaceuticals targeting neurological and cardiovascular conditions. Its structure supports the creation of sulfonamide-based drugs, which are known for their antimicrobial and enzyme-inhibiting properties. Also employed in research settings to develop novel ligands for receptor binding studies due to the presence of both amine and sulfonamide functional groups. Additionally, it serves as a building block in the preparation of fluorescent probes and imaging agents, where the amine group can be easily conjugated to dyes or labels. Its hydrochloride salt form enhances solubility and stability, making it suitable for use in aqueous reaction systems.
