Azanium nitrite

Azanium nitrite is an inorganic chemical compound with the molecular formula H4N2O2 and CAS number 13446-48-5. It has a molecular weight of 64.044 g/mol and belongs to the family of nitrogen-containing compounds. This substance is formed by the combination of azanium (ammonium-like) cations with nitrite anions, creating a crystalline salt structure that is commonly used in various industrial applications requiring nitrogen-oxygen chemistry.

Azanium nitrite typically appears as a white to pale yellow crystalline solid at room temperature. The compound is highly soluble in water due to its ionic nature, forming clear solutions. It has a molecular weight of 64.044 g/mol and contains both nitrogen and oxygen functional groups. The substance may exhibit hygroscopic properties, meaning it can absorb moisture from the atmosphere, and should be stored in dry conditions to maintain its stability.

Azanium nitrite is primarily used in chemical synthesis processes, particularly in reactions requiring nitrite functionality. It serves as a reagent in organic chemistry for diazotization reactions and as an intermediate in the production of various nitrogen-containing compounds. The substance finds applications in pharmaceutical manufacturing, dye production, and as a chemical intermediate in specialty chemical synthesis where controlled nitrite release is required.

Azanium nitrite should be handled using appropriate personal protective equipment including safety goggles, chemical-resistant gloves, and lab coats. Work in well-ventilated areas or under fume hoods to avoid inhalation of dust particles. Avoid contact with skin and eyes, and prevent ingestion. Use non-sparking tools and equipment when handling the substance. Always wash hands thoroughly after handling and ensure proper training on chemical safety procedures before use.

Azanium nitrite should be stored in a cool, dry place away from direct sunlight and heat sources. Keep containers tightly sealed to prevent moisture absorption and contamination. Store separately from strong acids, bases, and incompatible materials. Maintain storage temperatures below 25°C and ensure adequate ventilation in storage areas. Use original containers or chemically compatible storage vessels, and implement proper inventory management with clear labeling and dating.

In case of skin contact with azanium nitrite, immediately flush the affected area with plenty of water for at least 15 minutes and remove contaminated clothing. For eye contact, rinse thoroughly with clean water for several minutes and seek medical attention. If inhaled, move to fresh air immediately. In case of ingestion, do not induce vomiting and seek immediate medical attention. Always consult safety data sheets for specific first aid measures.

Azanium nitrite waste must be disposed of according to local and national hazardous waste regulations. Do not discharge into drains, waterways, or soil. Small quantities may be neutralized under controlled conditions by qualified personnel before disposal. Large quantities should be collected in appropriate containers and disposed of through licensed hazardous waste disposal companies. Always consult local environmental authorities for specific disposal requirements and maintain proper waste documentation.

Azanium nitrite is classified under ADR Class 5.1 as an oxidizing substance for transportation purposes. It must be packaged in UN-approved containers with proper labeling and documentation. Transport vehicles should be equipped with appropriate safety equipment and drivers must hold valid dangerous goods licenses. Ensure packages are secured to prevent damage during transit and maintain temperature controls if required. Follow all applicable transportation regulations for oxidizing materials.

Azanium nitrite is subject to standard chemical regulations including REACH registration requirements in Europe and CLP classification for hazard communication. While not currently listed as a Substance of Very High Concern (SVHC), users must comply with occupational safety regulations and maintain proper safety data sheets. Industrial users should implement appropriate risk management measures and ensure compliance with local chemical safety legislation and workplace exposure limits.
