Chemical Structure

S-acetyl-PEG3-phosphonic acid ethyl ester CAS 2173125-29-4 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.

S-acetyl-PEG3-phosphonic acid ethyl ester (CAS 2173125-29-4) is a high-purity analytical reference standard with the molecular formula C14H29O7PS and a molecular weight of 372.41 g/mol.

The molecular framework of S-acetyl-PEG3-phosphonic acid ethyl ester (C14H29O7PS) is characterized by a sulfone group, 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.
