Chemical Information
FooDB Name2-Methoxy-3-(2-methylpropyl)pyrazine
Description2-Methoxy-3-(2-methylpropyl)pyrazine belongs to the class of organic compounds known as methoxypyrazines. These are pyrazines containing a methoxyl group attached to the pyrazine ring. 2-Methoxy-3-(2-methylpropyl)pyrazine is a bell, earth, and galbanum tasting compound. 2-Methoxy-3-(2-methylpropyl)pyrazine has been detected, but not quantified in, several different foods, such as pepper (c. frutescens), peppers (Capsicum annuum), herbs and spices, common grapes (Vitis vinifera), and orange bell peppers (Capsicum annuum). This could make 2-methoxy-3-(2-methylpropyl)pyrazine a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on 2-Methoxy-3-(2-methylpropyl)pyrazine.
