Common Nametrans-4-phenylbut-3-en-2-one
DescriptionBenzylideneacetone, also known as trans-benzalacetone or 4-phenylbutenone, belongs to the class of organic compounds known as styrenes. These are organic compounds containing an ethenylbenzene moiety. Benzylideneacetone is an extremely weak basic (essentially neutral) compound (based on its pKa). Benzylideneacetone is a sweet, almond, and anise tasting compound. Outside of the human body,. Benzylideneacetone belongs to the family of Phenylpropenes. Benzylideneacetone is a potentially toxic compound. Benzylideneacetone is a flavouring ingredient. trans-4-phenylbut-3-en-2-one is found in Basella alba and Polygala senega. trans-4-phenylbut-3-en-2-one was first documented in 2011 (PMID: 21464604). These are compounds containing a phenylpropene moeity, which consists of a propene substituent bound to a phenyl group (PMID: 22692228).
