Bis(chloromethyl) ketone is a chemical substance with formula C
3H
4Cl
2O. It is a solid, and is used in the making of citric acid. Exposures such as contact or inhalation of bis(chloromethyl) ketone can result in irritation or damage to skin, eyes, throat, lungs, liver and kidneys, as well as headaches and fainting.[2] As both chlorine atoms tend to react at the same time, the compound is primarily useful for synthesis of various ring compounds.[3]

[edit]

Bis(chloromethyl) ketone is a substance which is classified as an extremely hazardous substance in the United States as defined in Section 302 of the U.S. Emergency Planning and Community Right-to-Know Act (42 U.S.C. 11002), and is subject to strict reporting requirements by facilities which produce, store, or use it in significant quantities.[4]
