Description
CATO supplies m-PEG3-Sulfone-PEG3-acid (CAS 1919045-04-7), a certified reference material (molecular formula C16H32O10S, MW 416.48 g/mol) for analytical method development and quality control.
The molecular framework of m-PEG3-Sulfone-PEG3-acid (C16H32O10S) 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.
As a certified reference material (CRM), m-PEG3-Sulfone-PEG3-acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
