Description
CATO manufactures (E)-3-(3-bromo-4-methoxyphenyl)-1-(2,4-dimethoxyphenyl)prop-2-en-1-one 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.
CATO supplies (E)-3-(3-bromo-4-methoxyphenyl)-1-(2,4-dimethoxyphenyl)prop-2-en-1-one (CAS 1228275-91-9), a certified reference material (molecular formula C18H17BrO4, MW 377.23 g/mol) for analytical method development and quality control.
Owing to a flavonoid core, a hydroxyl group, an ether linkage, bromine substitution, (E)-3-(3-bromo-4-methoxyphenyl)-1-(2,4-dimethoxyphenyl)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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
