Chemical Structure
Description
N-((1R,3S,4R,5R,6R)-5,6,8-trihydroxy-3-methoxy-7-(4-methoxyphenyl)-2-oxabicyclo[4.2.0]Octan-4-yl)acetamide (C17H23NO7) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. 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).
N-((1R,3S,4R,5R,6R)-5,6,8-trihydroxy-3-methoxy-7-(4-methoxyphenyl)-2-oxabicyclo[4.2.0]Octan-4-yl)acetamide (CAS 78489-61-9), molecular formula C17H23NO7 and molecular weight 353.37 g/mol, is a CATO reference standard with documented purity and traceability.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
