Chemical Structure

m-PEG3-phosphonic acid CAS 96962-42-4 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.

m-PEG3-phosphonic acid (CAS 96962-42-4) is a high-purity analytical reference standard with the molecular formula C7H17O6P and a molecular weight of 228.18 g/mol.

Owing to a carbohydrate-derived structure, a phosphate ester group, m-PEG3-phosphonic acid is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 228.18 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.
