Chemical Structure

Ethyl-beta-D-thiogalactopyranoside CAS 56245-60-4 chemical structure

Description

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.

CATO supplies Ethyl-beta-D-thiogalactopyranoside (CAS 56245-60-4), a certified reference material (molecular formula C8H16O5S, MW 224.27 g/mol) for analytical method development and quality control.

The molecular framework of Ethyl-beta-D-thiogalactopyranoside (C8H16O5S) is characterized by a sulfone group, a carboxylic acid group, 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.

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.
