Metabolite Identification
Common Name2-Butenal
Description2-Butenal (CAS: 4170-30-3), also known as crotonaldehyde, belongs to the class of organic compounds known as enals. These are alpha,beta-unsaturated aldehydes of the general formula RC=C-CH=O in which the aldehydic C=O function is conjugated to a C=C triple bond at the alpha,beta position. The (E)-form of 2-butenal predominates (>95%). 2-Butenal can undergo polycondensation with phenols to synthesize phenolic resins. It is an eye, skin, and mucous membrane irritant. (E)-2-Butenal is found in fruits and vegetables (e.g. tomato juice, strawberry aroma).
