Used as an intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the development of compounds with biological activity. It serves as a building block in the preparation of indole-based derivatives that are explored for their potential in medicinal chemistry, including anti-inflammatory and anticancer agents. Also utilized in the design of organic semiconductors and fluorescent dyes due to its aromatic structure and electron-donating properties. Commonly employed in research settings for structure-activity relationship studies involving indole scaffolds.
