Used in organic synthesis as an intermediate for pharmaceuticals and bioactive compounds. Serves as a building block in the development of serotonin receptor modulators and other neuroactive agents. Employed in research settings to construct indole-based scaffolds for drug discovery. Its chloro and methoxy functional groups allow for selective modifications, enabling the creation of diverse derivatives for structure-activity relationship studies. Also explored in the synthesis of fluorescent probes and imaging agents due to the inherent photophysical properties of the indole core.
