Description2-phenylbut-2-enal 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. 2-phenylbut-2-enal is an extremely weak basic (essentially neutral) compound (based on its pKa). 2-phenylbut-2-enal may be a unique S. cerevisiae (yeast) metabolite.
