Chemical Structure
Description
CATO supplies Methyl 3-4-6-tri-O-acetyl-2-deoxy-2-phthalimido-β-D-glucopyranoside (CAS 76101-13-8), a certified reference material (molecular formula C21H23NO10, MW 449.41 g/mol) for analytical method development and quality control.
The molecular framework of Methyl 3-4-6-tri-O-acetyl-2-deoxy-2-phthalimido-β-D-glucopyranoside (C21H23NO10) 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).
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.
