ethyl carbamate

They should not be confused with the specific substance urethane, also known as ethyl carbamate.

However, small quantities of ethyl carbamate are also used in laboratories as an anesthetic for animals.

Chemistry There are Canadian guidelines for ethyl carbamate in wines.

Polyurethanes neither contain nor are produced from ethyl carbamate.

Other foods and beverages prepared by means of fermentation also contain ethyl carbamate.

Soy sauce may contain ethyl carbamate, a Group 2A carcinogen.

Secondary reaction products include semicarbazide and ethyl carbamate.

Additionally, heating after bottling either during shipping or in preparation will cause ethyl carbamate levels to rise further.

Ethyl carbamate is not acutely toxic to humans, as shown by its use as a medicine.

Formerly, crosslinking agents for permanent press textile treatments were synthesized from ethyl carbamate.

The discovery of the widespread presence of ethyl carbamate in alcoholic beverages first occurred during the mid-1980s.

The first two and ethyl carbamate are very soluble in water, benzene, and ether.

Other research found that fermented food contains a carcinogenic by-product, ethyl carbamate (urethane).

Furthermore, some strains of yeast have been developed to help reduce ethyl carbamate during commercial production of alcoholic beverages.

Analysis of wine fermented using this yeast shows an 89 % reduction in ethyl carbamate levels compared to that of the host strain.

Polyurethane products often are simply called "urethanes", but should not be confused with ethyl carbamate, which is also called urethane.

Heating the azide in ethanol yields the ethyl carbamate via the Curtius rearrangement.

Along with this it is capable of sometimes producing biogenic amines or histamine and ethyl carbamate, which causes health risks.

The ring nitrogen is then protected as its ethyl carbamate by acylation with ethyl chloroformate (6).

By US FDA regulations, ethyl carbamate has been withdrawn from pharmaceutical use.

At that point, it is excreted externally where it is able to react with the alcohol to create ethyl carbamate.

Urethane (ethyl carbamate) was once produced commercially in the United States as an antineoplastic agent and for other medicinal purposes.

Ethyl carbamate (urethane)

Studies have shown that most, if not all, yeast-fermented alcoholic beverages contain traces of ethyl carbamate (15 ppb to 12 ppm).

Ethyl carbamate and methyl carbamate are carcinogenic to laboratory animals and should be handled with caution.
