Silver cation

Silver cation (CAS 14701-21-4), also referenced as Ag(1+), is the active ionic form of silver responsible for its antimicrobial and catalytic performance.

Where is Silver cation used?

• Water treatment: incorporated into filtration media and disinfection systems to control bacterial growth
• Mining: catalyst in hydrometallurgical processes, particularly oxidative leaching of ores to improve metal recovery yields
• Pharmaceutical and healthcare: silver cation-releasing materials in wound care products and antimicrobial coatings
• Biotechnology: control of microbial contamination in cell culture environments
• It also serves as a selective agent in certain diagnostic assay formats and specialized laboratory research.

Good to know: Silver cation is not an isolated compound; it is sourced through silver salt precursors such as silver nitrate or silver sulfate, which release the active ion in solution. USP and Ph. Eur. specifications are relevant for healthcare and biotech procurement.

Commercial specifications

• Generated in solution from silver salt precursors
• Precursors include silver nitrate or silver sulfate
• Grade selection depends on the downstream application
