4-Methylphenyl 4,6-O-Benzylidene-2,3-di-O-(4-methoxybenzyl)-beta-D-thiogalactopyranoside CAS 1293922-41-4

Description

The molecular framework of 4-Methylphenyl 4,6-O-Benzylidene-2,3-di-O-(4-methoxybenzyl)-beta-D-thiogalactopyranoside (C36H38O7S) is characterized by a sulfone group, 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 4-Methylphenyl 4,6-O-Benzylidene-2,3-di-O-(4-methoxybenzyl)-beta-D-thiogalactopyranoside (CAS 1293922-41-4), a certified reference material (molecular formula C36H38O7S, MW 614.75 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.

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.
