Indium sulfate

Indium sulfate (CAS 13464-82-9) is an inorganic indium salt used as a source compound in electronics manufacturing and catalytic processes. Diindium trisulfate is the stoichiometrically precise form most referenced in technical procurement contexts. It provides a soluble, processable form of indium for applications where controlled deposition or chemical conversion of the metal is required. In electronics, it functions as a precursor for indium-containing thin films.

Transparent conductive oxide layers, including indium tin oxide (ITO) coatings used in displays and photovoltaic devices, rely on this compound. Electroplating and electrodeposition processes use it to deposit indium metal onto substrates. These processes create corrosion-resistant or low-friction surface finishes for various industrial components. In catalysis research and specialty chemical synthesis, it acts as a Lewis acid catalyst for organic transformations.

Common applications include Friedel-Crafts-type reactions and ring-opening processes. Pharmaceutical and fine chemical manufacturers use it as a starting material for producing other indium compounds with defined purity profiles. Indium sulfate is supplied as a crystalline powder or solid. It is available in research-grade and technical-grade specifications, with high-purity grades offered for electronics and catalyst applications.

Standard high-purity grades are typically 99%+ or 99.99% metals basis. Packaging ranges from small laboratory quantities to kilogram-scale industrial lots depending on the specific requirements of the supplier.
