CAS ID #: 302-01-2, 1-Dimethylhydrazine; 57-14-7 1, 2-Dimethylhydrazine

Affected Organ Systems: Dermal (Skin), Hepatic (Liver), Respiratory (From the Nose to the Lungs)

Cancer Classification: NTP: Reasonably anticipated to be a human carcinogen

Please contact NTP, IARC, or EPA’s IRIS Hotline with questions on cancer and cancer classification.

Chemical Classification: Volatile organic compounds

Summary: Hydrazines are clear, colorless liquids with an ammonia-like odor. There are many kinds of hydrazine compounds, including hydrazine, 1,1-dimethylhydrazine, and 1,2-dimethylhydrazine. Small amounts of hydrazine occur naturally in plants. Most hydrazines are manufactured for use as rocket propellants and fuels, boiler water treatments, chemical reactants, medicines, and in cancer research. Hydrazines are highly reactive and easily catch fire.

  • Minimal Risk Levels (MRL)

    The MRL is an estimate of the daily human exposure to a hazardous substance that is likely to be without appreciable risk of adverse, non-cancer health effects over a specified duration of exposure. The information in this MRL serves as a screening tool to help public health professionals decide where to look more closely to evaluate possible risk of adverse health effects from human exposure.
