Used primarily as an intermediate in the synthesis of pharmaceuticals and biologically active compounds. Its structure supports the development of serotonin receptor modulators and other neuroactive agents. Commonly employed in research settings for the preparation of indole-based derivatives with potential antitumor, antiviral, or anti-inflammatory properties. Also utilized in the creation of fluorescent probes and sensors due to the indole core’s favorable photophysical characteristics. Suitable for use in cross-coupling reactions, enabling the construction of complex molecular architectures in medicinal chemistry.
