Azanium nitrite

Azanium nitrite is an inorganic compound with the molecular formula H4N2O2 and CAS number 13446-48-5. This chemical substance has a molecular weight of 64.044 g/mol and represents a salt formed between ammonium and nitrite ions. It appears as a crystalline solid at room temperature and is commonly used in various industrial applications requiring nitrite functionality.

Azanium nitrite is a white to pale yellow crystalline solid at room temperature with good water solubility. The compound has a molecular mass of 64.044 g/mol and contains both ammonium and nitrite functional groups. It typically exhibits hygroscopic properties, meaning it can absorb moisture from the atmosphere, and may have a slight ammonia-like odor due to its ammonium component.

Azanium nitrite is primarily used as a chemical intermediate in organic synthesis and industrial manufacturing processes. It serves as a source of nitrite ions in various chemical reactions, particularly in diazotization reactions and the production of dyes and pharmaceuticals. The compound is also utilized in metal treatment applications and as a corrosion inhibitor in certain industrial systems.

Azanium nitrite should be handled with standard laboratory safety precautions including wearing appropriate personal protective equipment such as safety glasses, gloves, and lab coats. Work in well-ventilated areas to avoid inhalation of dust or vapors. Avoid contact with skin and eyes, and prevent ingestion. Use proper handling techniques to minimize dust generation and ensure good housekeeping practices in the work area.

Azanium nitrite should be stored in a cool, dry, and well-ventilated area away from direct sunlight and heat sources. Keep containers tightly closed and protect from moisture due to its hygroscopic nature. Store away from incompatible materials such as strong acids, strong bases, and organic materials. Maintain storage temperatures below 25°C and ensure proper labeling of all containers.

In case of skin contact with azanium nitrite, immediately wash the affected area with plenty of water and soap for at least 15 minutes. For eye contact, flush eyes immediately with clean water for 15 minutes and seek medical attention. If inhaled, move the person to fresh air and seek medical advice if symptoms persist. In case of ingestion, do not induce vomiting and seek immediate medical attention.

Azanium nitrite disposal must comply with local, national, and EU waste regulations including the Waste Framework Directive. The compound should be treated as chemical waste and disposed of through licensed waste management companies. Do not discharge into drains, waterways, or soil. Contact specialized waste disposal services for proper treatment and disposal methods according to regional environmental regulations.

Azanium nitrite is classified under ADR Class 5.1 as an oxidizing substance for transportation purposes. This classification requires specific packaging, labeling, and documentation requirements during transport. Use appropriate UN-approved packaging and ensure proper hazard labels are displayed. Transport should comply with ADR regulations for oxidizing substances and follow established dangerous goods transportation protocols.

Azanium nitrite is subject to various European chemical regulations including REACH (Registration, Evaluation, Authorization and Restriction of Chemicals) and CLP (Classification, Labelling and Packaging) regulations. The substance is not currently listed as a Substance of Very High Concern (SVHC). Users must comply with safety data sheet requirements and proper classification obligations under EU chemical legislation.
