Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 331.16 g/mol gives 3-(4’-Bromophenyl)-7-methoxycoumarin distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 3-(4’-Bromophenyl)-7-methoxycoumarin (CAS 332104-52-6), a certified reference material (molecular formula C16H11BrO3, MW 331.16 g/mol) for analytical method development and quality control.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, a polycyclic aromatic system, 3-(4’-Bromophenyl)-7-methoxycoumarin is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 331.16 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).
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 3-(4’-Bromophenyl)-7-methoxycoumarin 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.
