Used as a catalyst in organic synthesis, particularly in Friedel-Crafts acylations and alkylations, enabling the formation of carbon-carbon bonds in pharmaceutical and fine chemical production. Serves as a precursor in the synthesis of indium-containing materials, including semiconductors and optoelectronic devices. Employed in the preparation of indium-based thin films for transparent conductive coatings, such as those used in touchscreens, LCDs, and solar cells. Also utilized in research for indium doping in nanomaterials and as a reagent in the preparation of other indium compounds.
