Silver citrate

Silver citrate (CAS 126-45-4 ) is an inorganic silver salt used as an antimicrobial and biocidal agent across pharmaceutical and biomedical applications. Trisilver citrate is a recognized alternative name buyers may encounter in technical literature and supplier documentation.

It functions by releasing silver ions in controlled concentrations to inhibit microbial growth in formulated products and treated materials. In pharmaceutical and wound care formulations, it serves as an active antimicrobial ingredient.

This compound is preferred where controlled silver ion release is required without the harshness associated with silver nitrate. Biomedical device manufacturers incorporate it into coatings and surface treatments to reduce microbial colonization.

It is frequently used on catheters, implants, and surgical instruments to maintain sterility. In biotechnology, it is used as a preservative component in reagent systems and biological media where low-toxicity antimicrobial protection is needed.

Research and diagnostic product developers also source it as a reference compound or active ingredient in antimicrobial testing protocols. The material is supplied as a white to off-white powder for various industrial uses.

It is available in pharmaceutical-grade and technical-grade specifications, with pharmaceutical-grade material meeting purity requirements relevant to drug substance and excipient applications.

Packaging is typically offered in small laboratory quantities through to kilogram-scale lots, reflecting its primary use in high-value, low-volume formulations. This ensures flexibility for both research and production needs.
