Used in pharmaceutical research as a key intermediate in the synthesis of serotonin receptor modulators, particularly targeting 5-HT3 and 5-HT4 receptors. It shows potential in the development of drugs for gastrointestinal disorders, such as irritable bowel syndrome, and central nervous system conditions including depression and anxiety. Its structure supports high receptor selectivity and improved metabolic stability, making it valuable in optimizing drug candidates for better efficacy and safety profiles. Also explored in the design of radiolabeled derivatives for neuroimaging studies.
