Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the production of analgesic and anti-inflammatory drugs. It plays an important role in the development of active pharmaceutical ingredients (APIs) due to its structural compatibility with nitrogen-containing heterocyclic compounds. Commonly utilized in research and development for central nervous system (CNS) agents, including antipsychotics and antidepressants. Also serves as a building block in the preparation of selective receptor agonists and antagonists. Its hydrochloride salt form enhances stability and solubility, making it suitable for use in various synthetic pathways.
