phenylcrotonaldehyde

Phenylcrotonaldehyde is an organic compound with the chemical formula C10H10O. It is an aromatic aldehyde, meaning it contains both a phenyl group and an aldehyde functional group. Specifically, it is a derivative of crotonaldehyde where a phenyl group is attached to the molecule. The position of the phenyl group can vary, leading to different isomers. The most common isomer is (E)-3-phenylbut-2-enal, also known as beta-phenylcrotonaldehyde.

Phenylcrotonaldehyde typically appears as a pale yellow liquid or solid, depending on the specific isomer and purity. It possesses a distinct odor. The compound can be synthesized through various organic reactions, often involving condensation of benzaldehyde derivatives with carbonyl compounds or through Wittig reactions.

This compound finds some limited applications in organic synthesis as an intermediate. It can be used in the preparation of other more complex organic molecules, including pharmaceuticals and fragrances. Its reactivity as an aldehyde allows it to participate in reactions such as nucleophilic addition and oxidation. Due to its aromatic and unsaturated nature, it can also undergo electrophilic aromatic substitution and addition reactions across the double bond. Information regarding its toxicity and environmental impact is generally limited and specific safety precautions should be taken when handling it.
