Used in pharmaceutical research as a key intermediate in the synthesis of bioactive molecules, particularly in the development of central nervous system agents. Its azide functional group allows for click chemistry applications, enabling efficient conjugation in drug discovery. Commonly employed in the preparation of benzazepine derivatives with potential therapeutic activity, including receptor agonists and antagonists. Also utilized in labeling and probing studies due to its reactivity in copper-catalyzed azide-alkyne cycloaddition (CuAAC) reactions.
