Chemical Structure

m-PEG4-Ms CAS 130955-37-2 chemical structure

Description

m-PEG4-Ms (CAS 130955-37-2) is a high-purity analytical reference standard with the molecular formula C10H22O7S and a molecular weight of 286.34 g/mol.

Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, m-PEG4-Ms is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 286.34 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

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

CATO manufactures m-PEG4-Ms under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
