Chemical Structure
Description
The molecular framework of 1-2-3-Tri-O-benzyl-4-6-O-benzylidene-α-D-mannopyranose (C34H34O6) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. 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).
CATO supplies 1-2-3-Tri-O-benzyl-4-6-O-benzylidene-α-D-mannopyranose (CAS 57783-75-2), a certified reference material (molecular formula C34H34O6, MW 538.63 g/mol) for analytical method development and quality control.
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.
