Used primarily as an intermediate in the synthesis of pharmaceuticals, particularly in the production of certain central nervous system agents and decongestants. It serves as a building block in asymmetric synthesis, enabling the development of enantiomerically pure drugs. Its structural features make it valuable in the preparation of bioactive molecules where a sterically hindered amine moiety is required. Also employed in research settings for developing novel amine-containing compounds with potential therapeutic activity. Due to its potential for misuse in the illicit production of controlled substances, its handling and use are strictly regulated.
