Description | Ethyl carbamate, also known as aethylurethan or uretan, belongs to the class of organic compounds known as carboximidic acids and derivatives. Carboximidic acids and derivatives are compounds containing a carboximidic group, with the general formula R-C(=NR1)OR2. Ethyl carbamate has been detected, but not quantified, in alcoholic beverages. This could make ethyl carbamate a potential biomarker for the consumption of these foods. Ethyl carbamate is formally rated as a probable carcinogen (by IARC 2A) and is also a potentially toxic compound. It is readily absorbed from the gastrointestinal tract and the skin. It also tends to induce specific mutations in the Kras oncogene in codon 61 of exon 2 including A:T transversions and A-->G transitions in the second base and A-->T transversions in the third base. Urethane, formerly marketed as an inactive ingredient in Profenil injection, was determined to be carcinogenic and was removed from the Canadian, US, and UK markets in 1963. If necessary, the person should shower and change contaminated clothing and shoes, and then must seek medical attention. In case of contact with eyes, irrigate opened eyes for several minutes under running water. Metabolism is mediated by cytochrome P450 2E1. |
