Hazard
A carcinogen (OSHA).
Physical properties
Colorless orthorhombic crystal; density 1.378 g/cm3; melts at 254°C; sparingly soluble in cold water 1.64% at 0°C and 3.41% at 25°C; more soluble inhot water; practically insoluble in alcohol (0.04% at 25°C).
General Description
Hydrazine sulfate salt is a potential anticachexia agent for treating cancer patients.
Potential Exposure
Used in analysis and refining of miner-als, rare metals, determination of arsenic in metals, as a .catalyst and an antioxidant, and in fungicides, germicides,and blood tests. Used as a catalyst for making acetatefibers.
First aid
If this chemical gets into the eyes, remove anycontact lenses at once and irri gate immediately for at least15 min, occasionally lifting upper and lower lids. Seek med-ical attention immediately. If this chemical contacts theskin, remove contaminated clothing and wash immediatelywith soap and water. Seek medical attention immediately. Ifthis chemical has been inhaled, remove from exposure,begin rescue breathing (using universal precautions, includ-ing resuscitation mask) if breathing has stopped and CPR ifheart action has stopped. Transfer promptly to a medicalfacility. When this chemical has been swallowed, get medi-cal attention. Give large quantities of water and inducevomiting. Do not make an unconscious person vomit. Asfirst aid for pulmonary edema, a doctor or authorized para-medic may consider administering a corticosteroid spray.Notetophysician:Treat formethemoglobinemia.Spectrophotometry may be required for precise determina-tion of levels of methemoglobin in urine. Pyridoxine(25 mg/kg) is an effective anticonvulsant for hydrazinepoisoning.
Carcinogenicity
Hydrazine and hydrazine sulfate are reasonably anticipated to be human carcinogens based on sufficient evidence of carcinogenicity from studies in experimental animals.
storage
(1) Color Code- Yellow Stripe (strong reducingagent): Reactivity Hazard; Store separately in an area iso-lated from flammables, combustibles, or other yellow-codedmaterials. (2) Color Code- White: Corrosive or ContactHazard; Store separately in a corrosion-resistant location.(3) Color Code- -Blue: Health Hazard/Poison: Store in asecure poison location. A regulated, marked area should beestablished where this chemical is handled, used, or storedin compliance with OSHA Standard 1910.1045. Store intightly closed containers in a cool, well-ventilated areaaway from oxidizers, bases.
Shipping
Hydrazinesulfatemustbelabeled“CORROSIVE." It falls in Hazard Class 8 and PackingGroup III.
Purification Methods
Its solubility in H2O is 3% at room temperature, but is very soluble in hot H2O. It is a suspected carcinogen. [Adams & Brown Org Synth Coll Vol I 309 1941, Audrieth & Nickles Inorg Synth I 90 1939.]
Incompatibilities
A strong reducing agent. Reacts with oxi-dizers, bases.
