Bis(chloromethyl) Ether

CAS ID #: 542-88-1

Affected Organ Systems: Neurological (Nervous System), Respiratory (From the Nose to the Lungs)

Cancer Effects: Known to be a Human Carcinogen

Chemical Classification: Nitrosamines/ethers/alcohols

Summary: Bis(chloromethyl) ether is a clear liquid with a strong unpleasant odor. It does not occur naturally. It dissolves easily in water, but degrades rapidly and readily evaporates into air. In the past, it was used to make several types of polymers, resins, and textiles, but its use is now highly restricted. Only small quantities of bis(chloromethyl) ether are produced in the United States. The small quantities that are produced are only used in enclosed systems to make other chemicals. However, small quantities of bis(chloromethyl) ether may be formed as an impurity during the production of another chemical, chloromethyl methyl ether.

    Succinctly characterizes the toxicologic and adverse health effects information for a hazardous substance.

  • 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.
