Common Name | Acetamide |

Description | Acetamide, also known as ethanamid or acetic acid amide, belongs to the class of organic compounds known as carboximidic acids. These are organic acids with the general formula RC(=N)-OH (R=H, organic group). Acetamide is a mousy tasting compound. Acetamide has been detected, but not quantified in, red beetroots (Beta vulgaris var. rubra). This could make acetamide a potential biomarker for the consumption of these foods. Acetamide is formally rated as a possible carcinogen (by IARC 2B) and is also a potentially toxic compound. Based on a literature review a significant number of articles have been published on Acetamide. |
