A β-aroylacrylic acid is a molecule of acrylic acid with an aroyl group attached at the β position.
Acrylic acid is the common name for propenoic acid, CH₂=CHCOOH.
In the common names of acids, the carbon atoms are numbered starting with the C next to the carboxyl group as α, β, γ, δ, etc. So the β position is at C-3.
An aroyl group is an aromatic acid ArCOOH minus the OH group: ArCO-. An example is the benzoyl group, C₆H₅CO-, derived from benzoic acid.
A typical β-aroylacrylic acid is β-benzoylacrylic acid, C₆H₅COCH=CHCOH.
