Used as a catalyst in organic synthesis, particularly in carbon-carbon bond formation reactions such as Friedel-Crafts alkylation and aldol condensation. Employed in the preparation of indium-containing semiconductors and thin films for optoelectronic devices. Serves as a precursor in chemical vapor deposition (CVD) processes to fabricate indium-based materials for solar cells and transparent conductive coatings. Also utilized in research for luminescent materials and coordination chemistry due to its Lewis acidic properties and ability to form complexes with various ligands.
