What are the main uses of Bismuth subnitrate (CAS: 10361-46-3)?

Bismuth subnitrate is primarily used in pharmaceuticals as an antacid and antidiarrheal agent. It also serves as a precursor in the synthesis of other bismuth compounds and is applied in industrial processes for its catalytic properties. Additionally, it is used in research for analytical chemistry and as a component in some food-grade stabilizers, though its primary role remains in medicinal applications.
