Description
The occurrence of 16981-20-7 2H-1-Benzopyran-2-one, 5,7-dihydroxy-8-(3-methyl-2-butenyl)-6-(2-methyl-1-oxopropyl)-4-phenyl- 5,7-dihydroxy-8-(3-methylbut-2-enyl)-6-(2-methylpropanoyl)-4-phenyl-chromen-2-one Mesuol NSC130114 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.
16981-20-7 2H-1-Benzopyran-2-one, 5,7-dihydroxy-8-(3-methyl-2-butenyl)-6-(2-methyl-1-oxopropyl)-4-phenyl- 5,7-dihydroxy-8-(3-methylbut-2-enyl)-6-(2-methylpropanoyl)-4-phenyl-chromen-2-one Mesuol NSC130114 (CAS 16981-20-7), molecular formula C24H24O5 and molecular weight 392.44 g/mol, is a CATO reference standard with documented purity and traceability.
16981-20-7 2H-1-Benzopyran-2-one, 5,7-dihydroxy-8-(3-methyl-2-butenyl)-6-(2-methyl-1-oxopropyl)-4-phenyl- 5,7-dihydroxy-8-(3-methylbut-2-enyl)-6-(2-methylpropanoyl)-4-phenyl-chromen-2-one Mesuol NSC130114 (C24H24O5) 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).
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.
