Description
6160-80-1 4-methylumbelliferone beta-D-glucuronide 4-MUG 4-Methylumbelliferyl glucuronide 4-methyl-2-oxo-2H-1-benzopyran-7-yl beta-D-glucopyranosiduronic acid 4-Methylumbelliferyl beta-glucuronide 4-Methylumbelliferone glucuronide CHEBI:1904 (CAS 6160-80-1) is a high-purity analytical reference standard with the molecular formula C16H16O9 and a molecular weight of 352.29 g/mol.
The molecular framework of 6160-80-1 4-methylumbelliferone beta-D-glucuronide 4-MUG 4-Methylumbelliferyl glucuronide 4-methyl-2-oxo-2H-1-benzopyran-7-yl beta-D-glucopyranosiduronic acid 4-Methylumbelliferyl beta-glucuronide 4-Methylumbelliferone glucuronide CHEBI:1904 (C16H16O9) 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.
