Chemical Structure

(2E)-1-(3-Bromophenyl)-3-(3,4,5-trimethoxyphenyl)prop-2-en-1-one CAS 358656-15-2 chemical structure

Description

Owing to a flavonoid core, a hydroxyl group, an ether linkage, bromine substitution, (2E)-1-(3-Bromophenyl)-3-(3,4,5-trimethoxyphenyl)prop-2-en-1-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 377.23 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).

(2E)-1-(3-Bromophenyl)-3-(3,4,5-trimethoxyphenyl)prop-2-en-1-one (CAS 358656-15-2) is a high-purity analytical reference standard with the molecular formula C18H17BrO4 and a molecular weight of 377.23 g/mol.

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.

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.
