Description
CATO supplies (E)-6-[1,3-Dihydro-1-hydroxy-6-methoxy-4-[(2-methoxyethoxy)methoxy]-7-methyl-3-oxo-5-isobenzofuranyl]-4-methyl-4-hexenoic Acid (CAS 172608-84-3), a certified reference material (molecular formula C21H28O9, MW 424.44 g/mol) for analytical method development and quality control.
(E)-6-[1,3-Dihydro-1-hydroxy-6-methoxy-4-[(2-methoxyethoxy)methoxy]-7-methyl-3-oxo-5-isobenzofuranyl]-4-methyl-4-hexenoic Acid (C21H28O9) contains a flavonoid core, 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
