Used in organic synthesis, particularly in the development of pharmaceuticals and bioactive compounds. Its structure serves as a building block for indole-based molecules, which are common in medicinal chemistry. It has potential applications in the synthesis of serotonin receptor modulators and other neuroactive agents. Also employed in research settings to develop fluorescent probes and dyes due to the inherent photophysical properties of the indole scaffold. Its amine group allows for easy functionalization, making it valuable in combinatorial chemistry and drug discovery.
