Chemical Structure
Description
PEG7-O-Ms (CAS 1217601-12-1), molecular formula C15H32O10S and molecular weight 404.47 g/mol, is a CATO reference standard with documented purity and traceability.
PEG7-O-Ms (C15H32O10S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions.
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), PEG7-O-Ms 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.
