Chemical Structure
Description
The molecular framework of 4-Methylumbelliferyl 2-acetamido-3,4,6-tri-O-acetyl-2-deoxy-a-D-glucopyranoside (C24H27NO11) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing 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).
4-Methylumbelliferyl 2-acetamido-3,4,6-tri-O-acetyl-2-deoxy-a-D-glucopyranoside (CAS 1174287-76-3), molecular formula C24H27NO11 and molecular weight 505.47 g/mol, is a CATO reference standard with documented purity and traceability.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
