Used in pharmaceutical research as an intermediate in the synthesis of serotonin receptor modulators and other neuroactive compounds. It serves as a building block for indole-based molecules with potential antidepressant, anxiolytic, or anti-inflammatory properties. Also employed in the development of novel kinase inhibitors and in studies exploring cell signaling pathways. Its nitrile group allows for further chemical modifications, making it valuable in medicinal chemistry for creating diverse compound libraries.
