Bismuth Subnitrate USP
Abstract:
Bismuth oxynitrate is the name applied to a number of compounds that contain Bi3+, nitrate ions and oxide ions and which can be considered as compounds formed from Bi2O3, N2O5 and H2O. Other names for bismuth oxynitrate include bismuth subnitrate and bismuthyl nitrate. In older texts bismuth oxynitrate is often simply described as BiONO3
Uses/Applications:
Used as a white pigment, in beauty care, and as a gentle disinfectant for internal and external use
