Bismuth subnitrate(CAS: 10361-46-3)

Bismuth subnitrate is a chemical compound with the formula Bi(NO3)3. It appears as a white, crystalline powder and is highly soluble in water. This compound is known for its low toxicity compared to other bismuth salts and is commonly used in pharmaceutical and industrial applications. Its properties include thermal stability and a mild antiseptic effect, making it suitable for specific medicinal formulations.

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.

Bismuth subnitrate is considered relatively safe when used as directed, with low acute toxicity. However, prolonged exposure or ingestion may cause gastrointestinal irritation. Safety precautions include wearing protective gloves and goggles, and ensuring proper ventilation during handling. It complies with regulatory standards for limited use in pharmaceuticals and is not classified as a hazardous substance under typical exposure conditions.

Bismuth subnitrate should be stored in a cool, dry place (ideally below 25°C) in airtight containers to prevent moisture absorption. It is sensitive to humidity and should be protected from light using opaque packaging. Storage in a well-ventilated area is recommended to maintain stability, and it should be kept away from incompatible materials to ensure long-term safety and efficacy.
