Indium(III) sulfate

Indium(III) sulfate (CAS 13464-82-9, EC 236-689-1) is an inorganic indium salt also referred to as indium sulfate or indium sulphate, with no assigned E-code. It is supplied as a grayish, deliquescent solid and is water-soluble, making it suitable for solution-based processing applications.

In electronics manufacturing, indium sulfate serves as a precursor in electroplating and thin-film deposition processes, where indium ions are reduced onto substrates to form conductive or transparent oxide layers. In catalysis research and pharmaceutical synthesis, it acts as a Lewis acid catalyst, activating organic substrates through coordination with electron-donating groups.

Indium(III) sulfate is available in technical and research grades and falls under REACH regulation (EC 236-689-1), requiring suppliers to provide a compliant Safety Data Sheet. It carries no FCC or Ph.Eur. designation. Standard packaging formats include sealed moisture-resistant containers, given the compound's deliquescent nature. HS code 2833 29 80 applies for EU import and export classification.
