Silver oxide

Silver oxide (CAS 20667-12-3), also known as silver monoxide, is an inorganic silver compound used across pharmaceutical synthesis, electronics manufacturing, and antimicrobial applications. It functions primarily as a mild oxidizing agent and a source of reactive silver ions, enabling controlled chemical transformations and biocidal action without handling complexity.

In pharmaceutical and fine chemical synthesis, it serves as a selective oxidant for converting primary alcohols and aldehydes, and as a reagent for preparing silver salts of organic acids. Electronics manufacturers use it as an active cathode material in silver oxide button cells, where its high energy density relative to cell volume suits hearing aids and precision instruments.

Antimicrobial formulations in medical devices and wound care products incorporate it to deliver sustained silver ion release for various clinical and industrial applications. In biotechnology, it functions as a catalyst support and precursor in the preparation of silver nanoparticles for research and diagnostic applications in modern laboratories.

Silver oxide is supplied as a dark brown to black powder in technical and reagent grades. High-purity grades meeting ACS or pharmaceutical-grade specifications are available. Packaging ranges from small laboratory quantities to multi-kilogram lots, with moisture-controlled packaging standard due to the compound's inherent light sensitivity during storage.
