Description
CATO manufactures 3-Hydroxy-4'-methoxyflavone 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 3-Hydroxy-4'-methoxyflavone (CAS 6889-78-7), a certified reference material (molecular formula C16H12O4, MW 268.26 g/mol) for analytical method development and quality control.
Owing to a flavonoid core, a hydroxyl group, an ether linkage, 3-Hydroxy-4'-methoxyflavone is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 268.26 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.
