Chemical Structure

(E)-Methyl 3-(4-chlorophenyl)acrylate CAS 20754-21-6 chemical structure

Description

The occurrence of (E)-Methyl 3-(4-chlorophenyl)acrylate is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

(E)-Methyl 3-(4-chlorophenyl)acrylate (CAS 20754-21-6) is a high-purity analytical reference standard with the molecular formula C10H9ClO2 and a molecular weight of 196.63 g/mol.

Based on its molecular formula C10H9ClO2, (E)-Methyl 3-(4-chlorophenyl)acrylate contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 196.63 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), (E)-Methyl 3-(4-chlorophenyl)acrylate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
