Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of serotonin receptor modulators and anti-migraine agents. It plays an important role in constructing indole-based scaffolds found in biologically active molecules. Commonly employed in research settings for the preparation of tryptamine and tryptophan derivatives. Also utilized in the production of agrochemicals and in the study of kinase inhibitors due to its ability to participate in cyclization and substitution reactions. Its nitrile and bromo functional groups allow for diverse chemical transformations, making it valuable in medicinal chemistry and drug discovery.
