Silver nitrate

Silver nitrate (CAS 7761-88-8), historically known as Lapis infernalis, is an inorganic silver salt produced by dissolving silver in nitric acid.

Where is Silver nitrate used?

• Electronics and PCB manufacturing: precursor for conductive silver coatings and mirror deposition
• Water treatment: chloride contamination testing and halide detection calibration
• Pharmaceutical and healthcare: topical preparations and medical device coatings
• Printing and photographic chemistry: reagent for silver-based imaging systems and specialty inks
• It functions as a primary source of ionic silver in industrial, analytical, and biomedical processes.

Good to know: Standard grades include USP, BP, and Ph. Eur. for pharmaceutical procurement and compliance; technical and reagent grades are also available.

Commercial specifications

• Packaging in amber glass or light-protected containers to prevent photodegradation during storage and transit
