Chemical Structure
Description
CATO supplies Methyl 2-O-Benzyl-3,4,6-tri-O-acetyl-beta-D-mannopyranoside (CAS 210297-58-8), a certified reference material (molecular formula C20H26O9, MW 410.42 g/mol) for analytical method development and quality control.
The molecular framework of Methyl 2-O-Benzyl-3,4,6-tri-O-acetyl-beta-D-mannopyranoside (C20H26O9) 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 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.
