Indium triacetate is primarily used as a catalyst in organic synthesis, particularly in reactions involving the formation of carbon-carbon bonds. It is effective in promoting cross-coupling reactions, such as the Suzuki-Miyaura coupling, which is widely used in the pharmaceutical industry for the synthesis of complex organic molecules. Additionally, it serves as a precursor for the preparation of indium-containing materials, including indium oxide, which is utilized in the production of transparent conductive coatings for electronic displays and solar cells. Its role in the synthesis of indium-based compounds also extends to applications in the field of optoelectronics, where it contributes to the development of light-emitting diodes (LEDs) and other semiconductor devices.
