Chemical Structure
Description
The molecular framework of (6R,7S)-8,8-Dimethyl-2-oxo-7,8-dihydro-2H,6H-pyrano[3,2-g]chromene-6,7-diyl bis(3-methylbut-2-enoate) (C24H26O7) 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).
CATO supplies (6R,7S)-8,8-Dimethyl-2-oxo-7,8-dihydro-2H,6H-pyrano[3,2-g]chromene-6,7-diyl bis(3-methylbut-2-enoate) (CAS 23027-48-7), a certified reference material (molecular formula C24H26O7, MW 426.46 g/mol) for analytical method development and quality control.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
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.
