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. Employed in the preparation of indium-containing materials for semiconductor applications, including transparent conductive oxides used in flat panel displays and solar cells. Serves as a precursor in the synthesis of other indium compounds used in electronic thin films and optoelectronic devices. Also utilized in research for indium doping in materials science and in some moisture-sensitive reactions where controlled reactivity is required.
