Description
Compared with other compounds in its class, the molecular weight of 226.66 g/mol gives (E)-3-(3,4-Dimethoxyphenyl)acryloyl chloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
(E)-3-(3,4-Dimethoxyphenyl)acryloyl chloride (CAS 141236-46-6), molecular formula C11H11ClO3 and molecular weight 226.66 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (E)-3-(3,4-Dimethoxyphenyl)acryloyl chloride (C11H11ClO3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
