Used as an intermediate in the synthesis of various pharmaceuticals and psychoactive substances, particularly in the production of substituted phenethylamines with potential neuromodulatory effects. Its structure serves as a backbone for compounds studied in neuropharmacology, especially those targeting serotonin receptors. Also employed in research settings to develop analogs for structure-activity relationship studies. Due to its role in synthesizing controlled substances, its use is often regulated and limited to authorized scientific and medicinal chemistry applications.
