Chemical Structure

PEG2-bis(phosphonic acid diethyl ester) CAS 500347-73-9 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 PEG2-bis(phosphonic acid diethyl ester) (CAS 500347-73-9), a certified reference material (molecular formula C12H28O9P2, MW 378.29 g/mol) for analytical method development and quality control.

The molecular framework of PEG2-bis(phosphonic acid diethyl ester) (C12H28O9P2) 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.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
