Chemical Structure

PEG3-bis(phosphonic acid diethyl ester) CAS 1807539-03-2 chemical structure

Description

CATO supplies PEG3-bis(phosphonic acid diethyl ester) (CAS 1807539-03-2), a certified reference material (molecular formula C14H32O10P2, MW 422.35 g/mol) for analytical method development and quality control.

The molecular framework of PEG3-bis(phosphonic acid diethyl ester) (C14H32O10P2) is characterized by a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage. 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.

CATO manufactures PEG3-bis(phosphonic acid diethyl ester) under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
