Toxicity Profile

Route of ExposureOral ; inhalation ; dermal
Mechanism of ToxicityAt least two mechanisms of action have been observed. One involves the direct binding of those hydrazines with a free amino group (hydrazine and 1,1-dimethylhydrazine) to key cellular molecules. Hydrazine reacts with alpha-keto acids such as vitamin B6 to form hydrazoines compounds. By binding to keto acids and forming hydrazones, hydrazine inhibits oxygen consumption with mitochondrial substrates in vitro. A second mechanism involves the generation of reactive species such as free radical intermediates or methyldiazonium ions as a result of metabolism.
MetabolismHydrazines are likely to be more rapidly absorbed into the blood after ingestion or exposure to the skin than after inhalation. Once in the blood, they are probably carried to all the tissues of the body. Soon after exposure, the levels of hydrazines in the tissues fall since they are metabolised in several products such as acetyl-, diacetylhydrazine, pyruvate hydrazone, urea, and acyclic compound (1,4,5,6-tetrahydro-6-oxo-3-pyridazine carboxylic acid). However, these metabolites interacts with some important proteins and might be harmful to the body. Some studies showed that metabolites and unchanged hydrazine leave the body within one day. Small amounts can also be found in the expired air.
Toxicity ValuesLD50: 60 mg/kg (Oral, Rat) LD50: 91 mg/kg (Dermal, Rabbit) LC50: 570 ppm over 4 hours (Inhalation, Rat)
Lethal Dose
Carcinogenicity (IARC Classification)2B, possibly carcinogenic to humans.
Minimum Risk LevelIntermediate Inhalation: 0.004 ppm
Health EffectsBreathing hydrazines for short periods may cause coughing and irritation of the throat and lungs, convulsions, tremors, or seizures. Breathing hydrazines for long periods may cause liver and kidney damage, as well as serious effects on reproductive organs. Eating or drinking small amounts of hydrazines may cause nausea, vomiting, uncontrolled shaking, inflammation of the nerves, drowsiness, or coma. (L154)
TreatmentInduced emesis, gastric lavage, use of saline cathartics, or activated charcoal are commonly used to decrease the gastrointestinal absorption of hydrazines. In general, these treatments are most effective when used within a few hours after oral exposure. Following dermal or ocular exposures to hydrazines, all contaminated clothing should be removed, and contacted skin should be washed immediately with soap and water. Eyes that have come in contact with hydrazines should be flushed with copious amounts of water. Contact lenses should be removed prior to flushing with water.
