Chemical Structure

2,3-Dihydroxypropyl-a-D-Galactopyranoside CAS 4649-46-1 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2,3-Dihydroxypropyl-a-D-Galactopyranoside.

CATO supplies 2,3-Dihydroxypropyl-a-D-Galactopyranoside (CAS 4649-46-1), a certified reference material (molecular formula C9H18O8, MW 254.23 g/mol) for analytical method development and quality control.

The molecular framework of 2,3-Dihydroxypropyl-a-D-Galactopyranoside (C9H18O8) is characterized by a carbohydrate-derived structure. 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.

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.
