Chemical Structure

m-PEG24-acid CAS 2248203-61-2 chemical structure

Description

m-PEG24-acid (CAS 2248203-61-2) is a high-purity analytical reference standard with the molecular formula C50H100O26 and a molecular weight of 1117.31 g/mol.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, m-PEG24-acid is typically white to off-white amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 1117.31 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

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.
