Bismuth nitrate is widely used in the production of bismuth compounds, which are essential in various industrial and chemical processes. It serves as a key precursor in the synthesis of bismuth-based catalysts, which are employed in organic reactions and environmental applications. In the pharmaceutical industry, it is utilized to create bismuth-containing drugs, particularly for treating gastrointestinal disorders like ulcers and Helicobacter pylori infections. Additionally, it finds application in the manufacturing of pigments and coatings, where it contributes to the production of pearlescent and iridescent effects. Bismuth nitrate is also used in analytical chemistry as a reagent for detecting and separating certain ions. Furthermore, it plays a role in the preparation of bismuth oxides, which are used in electronic ceramics and glass manufacturing.
