The occurrence of 1,4-Phenanthrenedione,10-(acetyloxy)-2-[2-(acetyloxy)-1-methylethyl]-4b,5,6,7,8,8a,9,10-octahydro-3-hydroxy-4b,8,8-trimethyl-,(4bS,8aS,10R)- 269742-39-4 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.
CATO supplies 1,4-Phenanthrenedione,10-(acetyloxy)-2-[2-(acetyloxy)-1-methylethyl]-4b,5,6,7,8,8a,9,10-octahydro-3-hydroxy-4b,8,8-trimethyl-,(4bS,8aS,10R)- 269742-39-4 (CAS 269742-39-4), a certified reference material (molecular formula C24H32O7, MW 432.51 g/mol) for analytical method development and quality control.
The molecular framework of 1,4-Phenanthrenedione,10-(acetyloxy)-2-[2-(acetyloxy)-1-methylethyl]-4b,5,6,7,8,8a,9,10-octahydro-3-hydroxy-4b,8,8-trimethyl-,(4bS,8aS,10R)- 269742-39-4 (C24H32O7) 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).
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.
