Hydrazine;sulfuric acid

Hydrazine sulfate is an inorganic chemical compound with the molecular formula H6N2O4S and CAS number 10034-93-2. It is the sulfuric acid salt of hydrazine, appearing as a white crystalline powder. With a molecular weight of 130.13 g/mol, this compound serves as a stable, less hazardous alternative to pure hydrazine in various industrial applications.

Hydrazine sulfate is a white crystalline solid that is highly soluble in water and slightly soluble in alcohol. It is odorless and stable under normal conditions. The compound has a molecular weight of 130.13 g/mol and decomposes upon heating rather than melting. It forms acidic aqueous solutions and exhibits good thermal stability at room temperature.

Hydrazine sulfate is used primarily as a reducing agent in chemical synthesis, metal plating processes, and as a precursor for hydrazine production. It serves applications in pharmaceuticals, agrochemicals manufacturing, and as a catalyst in various organic reactions. The compound is also utilized in analytical chemistry and research laboratories due to its stability and controlled reactivity compared to free hydrazine.

Hydrazine sulfate should be handled wearing appropriate personal protective equipment including safety goggles, chemical-resistant gloves, and protective clothing. Work in well-ventilated areas or under fume hoods to avoid inhalation of dust. Avoid contact with skin, eyes, and mucous membranes. Use non-sparking tools and prevent accumulation of static electricity during handling and transfer operations.

Hydrazine sulfate should be stored in a cool, dry, well-ventilated area away from heat sources and direct sunlight. Keep containers tightly closed and store separately from oxidizing agents, acids, and incompatible materials. Use original labeled containers and ensure storage areas are equipped with appropriate spill containment measures. Maintain storage temperatures below 25°C for optimal stability.

In case of skin contact, immediately remove contaminated clothing and wash affected area thoroughly with soap and water for at least 15 minutes. For eye contact, flush immediately with clean water for 15 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.

Hydrazine sulfate must be disposed of according to local, national, and international waste regulations as a chemical waste. Contact licensed waste disposal companies for proper treatment and disposal. Never discharge into drains, sewers, or natural water bodies. Small quantities can be neutralized under controlled conditions by qualified personnel before disposal through approved chemical waste channels.

Hydrazine sulfate is classified under ADR Class 6.1 (Toxic substances), Packing Group III for transport purposes. It must be packaged in UN-approved containers with proper labeling and documentation. Transport vehicles must comply with ADR regulations for toxic substances. Ensure proper segregation from incompatible materials during transport and maintain appropriate shipping documentation.

Hydrazine sulfate is subject to REACH regulation in Europe and requires appropriate registration for commercial use. It falls under CLP regulation for classification, labeling, and packaging requirements. The substance is not currently listed as a SVHC (Substance of Very High Concern). Users must comply with local occupational health and safety regulations and maintain safety data sheets.
