Silver citrate

Silver citrate (CAS 126-45-4) is an inorganic silver salt used as an antimicrobial and biocidal agent in pharmaceutical and biomedical applications. Also known as trisilver citrate.

Where is Silver citrate used?

• Pharmaceutical and wound care: active antimicrobial ingredient
• Biomedical devices: coatings and surface treatments that reduce microbial colonization
• Catheters, implants and surgical instruments: sterility maintenance
• Biotechnology: preservative component in reagent systems and biological media
• Research and diagnostics: reference compound or active ingredient in antimicrobial testing protocols
• It releases silver ions in controlled concentrations to inhibit microbial growth.

Good to know: Preferred where controlled silver ion release is required without the harshness associated with silver nitrate.

Commercial specifications

• Pharmaceutical grade meets purity requirements for drug substance and excipient applications
• Packaging from small laboratory quantities to kilogram-scale lots
