Chemical Structure

Sulfone-Bis-PEG4-acid CAS 2055024-37-6 chemical structure

Description

The occurrence of Sulfone-Bis-PEG4-acid is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Sulfone-Bis-PEG4-acid (CAS 2055024-37-6), a certified reference material (molecular formula C22H42O14S, MW 562.63 g/mol) for analytical method development and quality control.

The molecular framework of Sulfone-Bis-PEG4-acid (C22H42O14S) is characterized by a sulfone 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.

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.
