Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of antihistamines and antidepressants. Its structure supports the formation of bioactive molecules due to the presence of both aromatic and amine functionalities. Commonly employed in research settings for designing compounds with central nervous system activity. Also utilized in the preparation of fluorescent probes and dyes owing to its naphthalene core, which enhances photostability and emission properties. Shows potential in medicinal chemistry for structure-activity relationship studies targeting receptor antagonists.
