Description
CATO manufactures 3-(3’-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.
3-(3’-Bromophenyl)-7-methoxycoumarin (CAS 720674-57-7) is a high-purity analytical reference standard with the molecular formula C16H11BrO3 and a molecular weight of 331.16 g/mol.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, a polycyclic aromatic system, 3-(3’-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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
