Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 460.43 g/mol gives 1-Naphthol 2,3,4-Tri-O-acetyl-β-D-glucuronide Methyl Ester distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
1-Naphthol 2,3,4-Tri-O-acetyl-β-D-glucuronide Methyl Ester (CAS 18404-55-2), molecular formula C23H24O10 and molecular weight 460.43 g/mol, is a CATO reference standard with documented purity and traceability.
1-Naphthol 2,3,4-Tri-O-acetyl-β-D-glucuronide Methyl Ester (C23H24O10) 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.
