Chemical Structure

m-PEG3-SH CAS 31521-83-2 chemical structure

Description

The occurrence of m-PEG3-SH 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.

m-PEG3-SH (CAS 31521-83-2) is a high-purity analytical reference standard with the molecular formula C7H16O3S and a molecular weight of 180.27 g/mol.

m-PEG3-SH (C7H16O3S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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.
