Chemical Structure

Ms-PEG12-m CAS 1059604-93-1 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 Ms-PEG12-m (CAS 1059604-93-1), a certified reference material (molecular formula C26H54O15S, MW 638.76 g/mol) for analytical method development and quality control.

Based on its molecular formula C26H54O15S, Ms-PEG12-m contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 638.76 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry.

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.
