Used in organic synthesis as an intermediate for pharmaceuticals and agrochemicals. Serves as a building block in the development of bioactive molecules, particularly in the production of indole-based compounds with potential antimicrobial, antifungal, or anti-inflammatory properties. Commonly employed in research settings for the design of novel heterocyclic compounds and in the preparation of derivatives for structure-activity relationship studies. Also utilized in the synthesis of dyes and functional materials where halogenated indoles enhance electronic or structural characteristics.
