Description

The occurrence of (+)-Rubiginone B2 (3S)-3,4-Dihydro-8-methoxy-3-methylbenz[a]anthracene-1,7,12(2H)-trione 130548-10-6 Rubiginone B2 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 (+)-Rubiginone B2 (3S)-3,4-Dihydro-8-methoxy-3-methylbenz[a]anthracene-1,7,12(2H)-trione 130548-10-6 Rubiginone B2 (CAS 130548-10-6), a certified reference material (molecular formula C20H16O4, MW 320.34 g/mol) for analytical method development and quality control.

Structurally, (+)-Rubiginone B2 (3S)-3,4-Dihydro-8-methoxy-3-methylbenz[a]anthracene-1,7,12(2H)-trione 130548-10-6 Rubiginone B2 (C20H16O4) contains a flavonoid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 13.0, corresponding to approximately 13 ring(s) or double-bond equivalent(s). With a molecular weight of 320.34 g/mol, it falls into the moderately-high-molecular-weight range. 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.
