Used as a starting material in the synthesis of biologically active indole compounds, particularly in pharmaceutical research for developing drugs targeting the central nervous system, such as analgesics, anxiolytics, or antidepressants. Its structure enhances the ability to cross the blood-brain barrier and influences binding to specific receptors in the brain. It is employed in structure-activity relationship (SAR) studies of psychoactive agents, as well as in the development of new drugs with greater specificity and reduced side effects.
