Chemical Structure

m-PEG6-thiol CAS 441771-60-4 chemical structure

Description

m-PEG6-thiol (CAS 441771-60-4), molecular formula C13H28O6S and molecular weight 312.42 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, m-PEG6-thiol is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 312.42 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

CATO manufactures m-PEG6-thiol 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.
