(E)-N-(4-bromo-3-methylphenyl)-3-(2,3,4-trimethoxyphenyl)acrylamide CAS 329778-45-2 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 406.27 g/mol gives (E)-N-(4-bromo-3-methylphenyl)-3-(2,3,4-trimethoxyphenyl)acrylamide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

(E)-N-(4-bromo-3-methylphenyl)-3-(2,3,4-trimethoxyphenyl)acrylamide (CAS 329778-45-2) is a high-purity analytical reference standard with the molecular formula C19H20BrNO4 and a molecular weight of 406.27 g/mol.

(E)-N-(4-bromo-3-methylphenyl)-3-(2,3,4-trimethoxyphenyl)acrylamide (C19H20BrNO4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution. Halogen substitution raises its density and boiling point, 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.

CATO manufactures (E)-N-(4-bromo-3-methylphenyl)-3-(2,3,4-trimethoxyphenyl)acrylamide 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.
