(E)-4-(3-(2,4-Dimethoxyphenyl)-3-oxoprop-1-en-1-yl)benzoic acid CAS 1638521-29-5 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

CATO supplies (E)-4-(3-(2,4-Dimethoxyphenyl)-3-oxoprop-1-en-1-yl)benzoic acid (CAS 1638521-29-5), a certified reference material (molecular formula C18H16O5, MW 312.32 g/mol) for analytical method development and quality control.

(E)-4-(3-(2,4-Dimethoxyphenyl)-3-oxoprop-1-en-1-yl)benzoic acid (C18H16O5) contains a flavonoid core, a hydroxyl group, an ether linkage. 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).

CATO manufactures (E)-4-(3-(2,4-Dimethoxyphenyl)-3-oxoprop-1-en-1-yl)benzoic acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
