Description
Compared with other compounds in its class, the molecular weight of 254.24 g/mol gives 6,7-dihydroxy-4-phenylcoumarin distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
6,7-dihydroxy-4-phenylcoumarin (CAS 482-82-6), molecular formula C15H10O4 and molecular weight 254.24 g/mol, is a CATO reference standard with documented purity and traceability.
6,7-dihydroxy-4-phenylcoumarin (C15H10O4) contains a flavonoid core, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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 6,7-dihydroxy-4-phenylcoumarin 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.
