CAS 111-91-1

Bis(2-chloroethoxy)methane

Bis(2-chloroethoxy)methane is a man‑made chlorinated ether used mainly as a solvent and chemical intermediate. It can escape to air or water during manufacture, use, or disposal, so it matters for communities near industrial sites [1][2].

Where It Comes From

Produced for industrial processes; may be present in industrial waste streams and at hazardous waste sites [1][2].

How You Are Exposed

Breathing workplace air, skin contact during handling, or contact with contaminated air, soil, or water near production or waste facilities. Most consumers have low likelihood of direct exposure [1][2][3].

Why It Matters

Short-term exposure can irritate eyes, skin, and lungs; higher exposures may affect the nervous system, liver, and kidneys. Human data are limited, and major agencies have not issued a cancer classification for this chemical [2][3].

Who Is at Risk

Workers in chemical manufacturing or waste management; people living near industrial releases or poorly controlled hazardous waste sites [1][2].

How to Lower Your Exposure

At work, use ventilation and protective gear per safety guidance. At home, follow local water advisories; certified activated carbon filters can reduce many chlorinated organic chemicals in drinking water [4].
