Chemical Structure

Bis-PEG6-acid CAS 119189-70-7 chemical structure

Description

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

CATO supplies Bis-PEG6-acid (CAS 119189-70-7), a certified reference material (molecular formula C16H30O10, MW 382.40 g/mol) for analytical method development and quality control.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, Bis-PEG6-acid is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 382.40 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

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.
