Used in organic synthesis, particularly in the development of pharmaceuticals and bioactive compounds. It serves as a building block for indole-based molecules, which are common in medicinal chemistry due to their presence in many natural products and drugs. Its amine functional group allows for easy modification, enabling the creation of diverse derivatives for drug discovery. It has been explored in the synthesis of serotonin receptor ligands and other neuroactive agents. Also utilized in research settings to study structure-activity relationships in indole alkaloid analogs.
