Mercury(2+) dinitrate

Mercury(2+) dinitrate is an inorganic mercury salt with the chemical formula HgN2O6 and CAS number 10045-94-0. This compound has a molecular weight of 324.6 g/mol and consists of mercury in its +2 oxidation state combined with two nitrate ions. It is a highly toxic mercury compound that requires careful handling due to the inherent dangers associated with mercury-containing substances.

Mercury(2+) dinitrate is typically a white crystalline solid at room temperature. It is highly soluble in water, forming clear solutions. The compound is hygroscopic, meaning it readily absorbs moisture from the air. It decomposes upon heating, releasing toxic nitrogen oxides and mercury vapors. The substance is sensitive to light and should be protected from prolonged exposure to prevent degradation.

Mercury(2+) dinitrate is primarily used in analytical chemistry as a reagent for various chemical analyses and laboratory procedures. It serves as a mercury source in specialized industrial processes and can be used in the synthesis of other mercury compounds. Due to its high toxicity and environmental concerns, its applications are strictly limited and regulated, with many uses being phased out in favor of safer alternatives.

Mercury(2+) dinitrate requires extreme caution during handling due to its high toxicity. Always wear appropriate personal protective equipment including nitrile gloves, safety goggles, and protective clothing. Work in a well-ventilated area or under a fume hood to prevent inhalation of vapors or dust. Avoid skin contact and ingestion completely. Use non-metallic tools and containers, and ensure proper training before handling this hazardous substance.

Mercury(2+) dinitrate should be stored in a cool, dry place away from direct sunlight and heat sources. Keep the container tightly sealed to prevent moisture absorption and contamination. Store separately from organic materials, reducing agents, and incompatible substances. The storage area should be well-ventilated and equipped with appropriate containment measures. Regular inspection of containers for signs of deterioration is essential for safe storage.

Immediate action is crucial in case of contact with mercury(2+) dinitrate. For skin contact, remove contaminated clothing and flush the affected area with plenty of water for at least 15 minutes. If inhaled, move to fresh air immediately. In case of eye contact, rinse thoroughly with water. For ingestion, do not induce vomiting and seek immediate medical attention. Always consult a physician after any exposure incident.

Mercury(2+) dinitrate requires specialized disposal as hazardous waste due to its mercury content and toxicity. Never dispose of it through regular waste streams or pour it down drains. Contact licensed hazardous waste disposal companies for proper treatment and disposal. The waste must be properly labeled and documented according to local environmental regulations. Recovery and recycling of mercury may be required in some jurisdictions to minimize environmental impact.

Mercury(2+) dinitrate is classified under ADR Class 6.1 (toxic substances), Packing Group II, indicating its high toxicity during transport. It must be packaged in approved containers meeting UN specifications and properly labeled with appropriate hazard markings. Transport vehicles require proper documentation, emergency response information, and compliance with dangerous goods regulations. Only trained personnel should handle the transportation of this hazardous material.

Mercury(2+) dinitrate is subject to strict regulations due to its mercury content and toxicity. It falls under various environmental and chemical safety regulations including restrictions on use, handling, and disposal. The substance requires compliance with occupational health standards and may be subject to licensing requirements in some jurisdictions. Export and import may be restricted under international mercury control agreements and national chemical safety legislation.

Mercury(2+) dinitrate is available through specialized chemical distributors in Europe, including OYSI, which supplies technical chemicals to industrial and research customers. Due to its hazardous nature and regulatory restrictions, purchase typically requires proper licensing, end-use declarations, and compliance with safety regulations. Buyers must demonstrate legitimate industrial or research applications and appropriate handling capabilities before procurement is possible.
