Bismuth Subnitrate

Bismuth subnitrate is an inorganic compound typically appearing as a white or slightly yellowish powder. It is composed of bismuth, oxygen, and nitrate groups. This compound is known for its basicity and is often used in various industrial and pharmaceutical applications. Bismuth subnitrate is slightly soluble in water but readily soluble in acids, forming bismuth nitrate in solution.

Applications

• Pharmaceuticals:
  • Widely used in medicinal preparations for its astringent and antibacterial properties. It is a key ingredient in some over-the-counter products used to treat gastrointestinal issues like diarrhea, nausea, and upset stomach.
  • Commonly found in bismuth-containing compounds for treating Helicobacter pylori infections, peptic ulcers, and other related conditions.
• Cosmetics:
  • Used as a pigment in cosmetics, particularly in powders and other formulations, due to its white color and opacity.
• Laboratory Reagent:
  • Employed in analytical chemistry and as a precursor for other bismuth compounds in research and development.
• Pyrotechnics:
  • Occasionally used in the production of fireworks and other pyrotechnic devices, contributing to the formulation’s stability and color effects.

Handling and Safety

• Handling:
  • Use appropriate personal protective equipment (PPE), such as gloves, safety goggles, and lab coats, to avoid direct contact.
  • Handle in a well-ventilated area or under a fume hood to prevent inhalation of dust particles.
  • Avoid generating dust; if dust is generated, use suitable containment methods to minimize exposure.
• Storage:
  • Store in a cool, dry, and well-ventilated place, away from incompatible materials such as strong acids and bases.
  • Keep the container tightly closed to prevent moisture absorption and contamination.
• Safety Precautions:
  • Inhalation: May cause respiratory irritation. If inhaled, move to fresh air immediately and seek medical attention if symptoms persist.
  • Skin Contact: May cause skin irritation. Wash thoroughly with soap and water if contact occurs.
  • Eye Contact: Can cause eye irritation. Rinse immediately with plenty of water for at least 15 minutes, and seek medical attention if irritation persists.
  • Ingestion: Harmful if swallowed. Seek immediate medical attention and do not induce vomiting unless instructed by medical personnel.
• Disposal:
  • Dispose of in accordance with local, regional, and national regulations. Avoid release into the environment.

First Aid Measures

• Inhalation: Move to fresh air immediately. Seek medical attention if breathing difficulties occur.
• Skin Contact: Wash skin thoroughly with soap and water. Remove contaminated clothing.
• Eye Contact: Flush eyes with plenty of water for at least 15 minutes. Seek medical attention if irritation persists.
• Ingestion: Rinse mouth with water. Do not induce vomiting and seek immediate medical attention.
