CATO supplies (3r,4r)-4-(7-methoxy-2-oxo-2h-chromen-8-yl)-2-methyl-1-butene-3,4 -diyl Diacetate 51650-59-0 (CAS 51650-59-0), a certified reference material (molecular formula C19H20O7, MW 360.36 g/mol) for analytical method development and quality control.
The molecular framework of (3r,4r)-4-(7-methoxy-2-oxo-2h-chromen-8-yl)-2-methyl-1-butene-3,4 -diyl Diacetate 51650-59-0 (C19H20O7) is characterized by a flavonoid core, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
