| Common Name | 3,4-Dimethylthiophene |
|---|
| Description | 3,4-Dimethylthiophene belongs to the class of organic compounds known as heteroaromatic compounds. Heteroaromatic compounds are compounds containing an aromatic ring where a carbon atom is linked to an hetero atom. 3,4-Dimethylthiophene has been detected, but not quantified in, garden onions (Allium cepa). This could make 3,4-dimethylthiophene a potential biomarker for the consumption of these foods. Based on a literature review a significant number of articles have been published on 3,4-Dimethylthiophene. |
