(E)-2-(2-Methoxyphenyl)-3-phenyl-2-propenoic acid (E)-2-(2-methoxyphenyl)-3-phenylacrylic acid 1657-65-4 CAS 1657-65-4 chemical structure

Description

The occurrence of (E)-2-(2-Methoxyphenyl)-3-phenyl-2-propenoic acid (E)-2-(2-methoxyphenyl)-3-phenylacrylic acid 1657-65-4 is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

(E)-2-(2-Methoxyphenyl)-3-phenyl-2-propenoic acid (E)-2-(2-methoxyphenyl)-3-phenylacrylic acid 1657-65-4 (CAS 1657-65-4), molecular formula C16H14O3 and molecular weight 254.28 g/mol, is a CATO reference standard with documented purity and traceability.

(E)-2-(2-Methoxyphenyl)-3-phenyl-2-propenoic acid (E)-2-(2-methoxyphenyl)-3-phenylacrylic acid 1657-65-4 (C16H14O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
