Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of central nervous system agents and analgesics. Its structure supports the creation of bioactive molecules due to the presence of a reactive methylene group and a basic nitrogen center. Commonly employed in medicinal chemistry for building nitrogen-containing heterocycles. Also utilized in research settings for the preparation of novel psychoactive substances and receptor ligands, especially targeting dopamine and sigma receptors. Its hydrochloride salt form enhances stability and solubility, making it suitable for solution-phase reactions.
