Chemical Structure
Description
The occurrence of 6-Methoxy-3-(4'-methoxyphenyl)coumarin is closely related to a flavonoid core, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
6-Methoxy-3-(4'-methoxyphenyl)coumarin (CAS 263364-71-2), molecular formula C17H14O4 and molecular weight 282.29 g/mol, is a CATO reference standard with documented purity and traceability.
6-Methoxy-3-(4'-methoxyphenyl)coumarin (C17H14O4) 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
