Indium sulfate

Indium sulfate (CAS 13464-82-9) is an inorganic indium salt used as a source compound in electronics manufacturing and catalytic processes. Also known as diindium trisulfate.

Where is Indium sulfate used?

• Electronics: precursor for indium-containing thin films
• Transparent conductive oxide layers, including indium tin oxide (ITO) coatings for displays and photovoltaic devices
• Electroplating and electrodeposition: deposits indium metal onto substrates for corrosion-resistant or low-friction finishes
• Catalysis research and specialty chemical synthesis: Lewis acid catalyst for organic transformations such as Friedel-Crafts-type reactions and ring-opening processes
• Pharmaceutical and fine chemical manufacturers use it as a starting material for other indium compounds with defined purity profiles.

Good to know: Diindium trisulfate is the stoichiometrically precise form most referenced in technical procurement contexts.

Commercial specifications

• High-purity grades typically 99%+ or 99.99% metals basis
• Packaging from small laboratory quantities to kilogram-scale industrial lots
