Chemical Structure
Description
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system, 3-(3-chlorophenyl)but-2-enoic acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 196.63 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
3-(3-chlorophenyl)but-2-enoic acid (CAS 91552-07-7) is a high-purity analytical reference standard with the molecular formula C10H9ClO2 and a molecular weight of 196.63 g/mol.
