Chemical Structure

PEG3-bis-(ethyl phosphonate) CAS 160625-24-1 chemical structure

Description

PEG3-bis-(ethyl phosphonate) (C16H36O9P2) contains a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions.

PEG3-bis-(ethyl phosphonate) (CAS 160625-24-1) is a high-purity analytical reference standard with the molecular formula C16H36O9P2 and a molecular weight of 434.40 g/mol.

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.
