Used in organic synthesis as a building block for pharmaceuticals and biologically active compounds. Serves as an intermediate in the preparation of alkaloids and neuroactive substances. Employed in research settings to develop compounds with potential antidepressant, anti-inflammatory, or neuroprotective properties. Also utilized in the synthesis of certain vasodilators and cardiovascular agents due to its structural similarity to catecholamine derivatives. Commonly applied in medicinal chemistry for structure-activity relationship (SAR) studies involving phenethylamine-based molecules.
