Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
5,7-Dimethoxy-4-methyl-2H-chromen-2-one (CAS 6093-80-7) is a high-purity analytical reference standard with the molecular formula C45H72O16 and a molecular weight of 869.04 g/mol.
5,7-Dimethoxy-4-methyl-2H-chromen-2-one (C45H72O16) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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).
CATO manufactures 5,7-Dimethoxy-4-methyl-2H-chromen-2-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.
