Metabolite Identification
Common Name2-Ethylbutanal
Description2-Ethylbutanal belongs to the class of organic compounds known as organic oxides. These are organic compounds containing an oxide group. 2-Ethylbutanal is a sweet, cocoa, and ethereal tasting compound. 2-Ethylbutanal has been detected, but not quantified in, several different foods, such as breakfast cereal, cereals and cereal products, fruits, mollusks, and potatos (Solanum tuberosum). This could make 2-ethylbutanal a potential biomarker for the consumption of these foods. Based on a literature review a small amount of articles have been published on 2-Ethylbutanal.
