Used in organic synthesis as an intermediate for pharmaceuticals and bioactive compounds. Its structure supports the development of indole-based derivatives with potential antitumor, antimicrobial, and anti-inflammatory activities. Commonly employed in the preparation of fluorescent dyes and sensors due to its conjugated system that enhances optical properties. Also utilized in coordination chemistry as a ligand for metal complexes in catalysis. Shows promise in agrochemical research for designing new plant growth regulators.
