Used primarily as a pharmaceutical intermediate in the synthesis of analgesic and antitussive agents. It serves as a key building block in the production of certain opioid receptor modulators, contributing to the development of centrally acting pain relievers and cough suppressants. Its structure allows for derivatization into active compounds that interact with neurological pathways involved in pain and cough regulation. Commonly utilized in research settings for developing new therapeutic candidates with improved efficacy and reduced side effects.
