Natural Product Identification
Common Name4-Methyl-2-phenyl-2-pentenal
Description4-Methyl-2-phenyl-2-pentenal, also known as fema 3200, belongs to the class of organic compounds known as phenylacetaldehydes. Phenylacetaldehydes are compounds containing a phenylacetaldehyde moiety, which consists of a phenyl group substituted at the second position by an acetalydehyde. 4-Methyl-2-phenyl-2-pentenal is an extremely weak basic (essentially neutral) compound (based on its pKa). 4-Methyl-2-phenyl-2-pentenal is a sweet, cocoa, and nutty tasting compound. Outside of the human body, 4-Methyl-2-phenyl-2-pentenal has been detected, but not quantified in, several different foods, such as tea, crustaceans, potato, green vegetables, and nuts. 4-Methyl-2-phenyl-2-pentenal is found in Theobroma cacao. This could make 4-methyl-2-phenyl-2-pentenal a potential biomarker for the consumption of these foods.
