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, forming white crystalline solid with a molecular weight of 130.13 g/mol. This compound is primarily used as a chemical intermediate and reducing agent in various industrial processes, offering better stability compared to free hydrazine base.

Hydrazine sulfate is a white crystalline solid that is highly soluble in water and slightly soluble in alcohol. It has a molecular weight of 130.13 g/mol and decomposes at elevated temperatures rather than melting. The compound is odorless or has a faint ammonia-like odor and exhibits good thermal stability under normal conditions, making it easier to handle than free hydrazine.

Hydrazine sulfate is used as a chemical intermediate in pharmaceutical synthesis, as a reducing agent in analytical chemistry, and in the production of various organic compounds. It serves as a precursor for manufacturing pesticides, herbicides, and other nitrogen-containing chemicals. Additionally, it finds applications in metal treatment processes and as a catalyst in certain chemical reactions where controlled reducing conditions are required.

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

Hydrazine sulfate should be stored in a cool, dry, well-ventilated area away from heat sources and incompatible materials. Keep containers tightly sealed and protected from moisture and light. Store away from strong oxidizing agents, acids, and metals. Maintain storage temperatures below 25°C and ensure proper labeling of containers. Use appropriate storage facilities that comply with local chemical storage regulations.

In case of skin contact with hydrazine sulfate, immediately remove contaminated clothing and wash the affected area thoroughly with soap and water for at least 15 minutes. For eye contact, rinse immediately with plenty of clean water for 15 minutes and seek medical attention. If inhaled, move the person to fresh air and seek medical advice if respiratory irritation occurs. Seek immediate medical attention for ingestion.

Hydrazine sulfate disposal must be conducted according to local, national, and international waste regulations. The compound should not be discharged into drains, waterways, or soil. Contact licensed waste disposal companies for proper treatment and disposal. Small quantities may be neutralized and disposed of according to laboratory waste procedures, while larger amounts require specialized hazardous waste handling and disposal protocols.

Hydrazine sulfate is classified under ADR Class 6.1 (Toxic substances), Packing Group III for transportation purposes. It must be packaged in approved containers with proper hazard labels and documentation. Transport vehicles should be equipped with appropriate safety equipment and emergency response materials. Drivers must hold valid dangerous goods transportation certificates, and shipments must comply with international dangerous goods regulations.

Hydrazine sulfate is subject to various chemical regulations including REACH registration requirements in Europe. It must comply with CLP regulation for classification, labeling, and packaging. The substance is not currently listed as a Substance of Very High Concern (SVHC). Users must maintain safety data sheets and follow workplace exposure limits where established by national authorities.
