Used in organic synthesis as an intermediate for pharmaceuticals and bioactive compounds. Serves as a building block in the preparation of indole-based derivatives with potential medicinal properties, including anticancer, antimicrobial, and anti-inflammatory agents. Commonly employed in the development of serotonin receptor modulators and kinase inhibitors. Also utilized in materials science for constructing fluorescent dyes and optoelectronic materials due to its conjugated aromatic structure.
