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 contains mercury in its +2 oxidation state combined with nitrate anions. It is classified as a toxic substance under ADR transport regulations (Class 6.1, Group II) due to the presence of mercury, making it subject to strict handling and transport requirements.

Mercury(2+) dinitrate typically appears as white crystalline solid at room temperature. Like most mercury nitrates, it is highly soluble in water and polar solvents. The compound is hygroscopic, meaning it readily absorbs moisture from air. It decomposes upon heating, releasing toxic mercury vapors and nitrogen oxides. The presence of mercury makes this compound particularly hazardous, requiring careful consideration of its physical properties during handling and storage.

Mercury(2+) dinitrate is primarily used in specialized analytical chemistry applications and as a reagent in laboratory synthesis. It serves as a mercury source in certain chemical reactions and may be used in the preparation of other mercury compounds. Due to environmental and health concerns associated with mercury compounds, its industrial applications are increasingly restricted, and it is mainly limited to specific research and analytical purposes where mercury is essential.

Mercury(2+) dinitrate requires extreme caution during handling due to mercury toxicity. Essential protective equipment includes nitrile gloves, safety goggles, and lab coats. Work must be conducted in well-ventilated areas or fume hoods to prevent vapor inhalation. Avoid skin contact and ingestion completely. Use non-sparking tools and prevent contamination of work surfaces. All personnel should be trained in mercury safety protocols and emergency procedures before handling this compound.

Mercury(2+) dinitrate should be stored in tightly sealed containers in a cool, dry, well-ventilated area away from heat sources and direct sunlight. Keep separate from incompatible materials such as reducing agents, organic compounds, and metals. Storage areas must be equipped with appropriate containment measures for potential spills. Containers should be clearly labeled and stored in secondary containment systems to prevent environmental contamination in case of leakage.

In case of skin contact with mercury(2+) dinitrate, immediately remove contaminated clothing and flush the affected area with plenty of water for at least 15 minutes. If inhaled, move the person to fresh air immediately and seek medical attention. For eye contact, rinse thoroughly with water for several minutes. Never induce vomiting if ingested. Seek immediate medical attention in all cases of exposure, informing healthcare providers about the mercury compound involved.

Mercury(2+) dinitrate must be disposed of as hazardous waste through licensed waste management facilities specializing in mercury-containing materials. Never dispose of this compound in regular trash or down drains due to severe environmental contamination risks. Collection and disposal must comply with local and European waste regulations including the Mercury Regulation. Contact certified waste disposal companies experienced in handling mercury compounds for proper collection, treatment, and disposal procedures.

Mercury(2+) dinitrate is classified under ADR as Class 6.1 (toxic substances), Packing Group II, indicating moderate toxicity requiring specific transport precautions. Packaging must meet UN specification standards for toxic substances, with proper labeling including toxic hazard symbols. Transport vehicles require appropriate documentation, emergency information, and driver training for hazardous materials. Shipments must comply with quantity limitations and routing restrictions as specified in ADR regulations.

Mercury(2+) dinitrate is subject to strict European regulations including the EU Mercury Regulation, which restricts manufacturing, import, and export of mercury compounds. Under REACH regulation, it requires registration for commercial use. CLP classification applies for hazard communication and labeling. Additional restrictions may apply under national legislation regarding mercury compounds. Users must ensure compliance with occupational exposure limits and environmental protection requirements specific to mercury-containing substances.

Mercury(2+) dinitrate can be purchased through OYSI, a specialized European distributor of chemical products with expertise in hazardous materials. OYSI provides proper documentation, regulatory compliance support, and safe packaging for mercury compounds. Due to strict mercury regulations, purchases typically require end-use declarations and compliance verification.
