Used in research as a biochemical tool to study serotonin receptor activity due to its structural similarity to serotonin. It serves as an intermediate in the synthesis of neuropharmacological compounds, particularly those targeting central nervous system disorders. Its sulfonamide and amine groups allow for derivatization in medicinal chemistry, enabling the development of compounds with potential antidepressant or anxiolytic effects. Also employed in assays to investigate enzyme inhibition, especially in monoamine transport systems.
