Chemical Structure

m-PEG3-OMs CAS 74654-05-0 chemical structure

Description

The occurrence of m-PEG3-OMs 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.

CATO supplies m-PEG3-OMs (CAS 74654-05-0), a certified reference material (molecular formula C8H18O6S, MW 242.29 g/mol) for analytical method development and quality control.

Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, m-PEG3-OMs is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 242.29 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
