| Common Name | 2,2-Dimethyloxirane |
|---|
| Description | 2,2-Dimethyloxirane, also known as 2-MEP, belongs to the class of organic compounds known as epoxides. Epoxides are compounds containing a cyclic ether with three ring atoms(one oxygen and two carbon atoms). 2,2-Dimethyloxirane has been detected, but not quantified in, herbs and spices. This could make 2,2-dimethyloxirane a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on 2,2-Dimethyloxirane. |
