Used primarily as a building block in organic synthesis, especially in the preparation of pharmaceuticals and agrochemicals. It serves as an intermediate in the development of certain bioactive molecules due to the presence of both an amine group and a naphthyl ring system, which can enhance binding affinity in biological systems. Its hydrochloride salt form improves stability and solubility, making it suitable for use in reaction schemes requiring polar media. Also employed in research settings for the synthesis of fluorescent probes and labeled compounds, leveraging the inherent fluorescence of the naphthalene moiety.
