Chloroacetamide (2-chloroacetamide) is a chlorinated organic compound with the molecular formula {{chem2|ClCH2CONH2|auto=1}}. It is a colorless solid although older samples appear yellow. It has a characteristic odor and is readily soluble in water.[http://www.inchem.org/documents/icsc/icsc/eics0640.htm 2-Chloroacetamide] It has the structure {{chem2|Cl\sCH2\sC(\dO)\sNH2}}.

Production

Chloroacetamide is produced by ammonolysis of esters of chloroacetic acid:{{Ullmann |author = Koenig, G. |author2 = Lohmar, E. |author3 = Rupprich, N. |title = Chloroacetic Acids |doi = 10.1002/14356007.a06_537}}{{cite journal |first1=W.

Uses

Chloroacetamide has been used as an herbicide,[http://www.epochem.com/products/agroHerbicides.htm Herbicides - Epochem] {{webarchive|url=https://web.archive.org/web/20080520105742/http://www.epochem.com/products/agroHerbicides.htm |date=2008-05-20}} preservative.[http://www.chemicalsubstanceschimiques.gc.ca/challenge-defi/batch-lot-5/79-07-2_e.html Acetamide, 2-chloro- - Government of Canada] {{webarchive|url=https://web.archive.org/web/20090131112114/http://chemicalsubstanceschimiques.gc.ca/challenge-defi/batch-lot-5/79-07-2_e.html |date=2009-01-31}} and in the manufacturing of pharmaceuticals.

Hazards

Chloroacetamide is toxic, irritates eyes and skin, and may cause an allergic reaction. It is suspected of reproductive toxicity and teratogenicity.{{cite web | url = http://ansm.sante.fr/content/download/41931/545388/version/1/file/dps-120625-Chloroacetamide-du-14062012.pdf | publisher = Agence Nationale de Sécurité du Médicament et des Produits de Santé | language = fr | title = Decisiondu 14 juin 2012 | access-date = 2012-07-03 | archive-date = 2013-05-23 | archive-url = https://web.archive.org/web/20130523054342/http://ansm.sante.fr/content/download/41931/545388/version/1/file/dps-120625-Chloroacetamide-du-14062012.pdf | url-status = dead}}
