Chemical Structure
Description
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.
CATO supplies Glycol dimercaptoacetate (CAS 123-81-9), a certified reference material (molecular formula C6H10O4S2, MW 210.27 g/mol) for analytical method development and quality control.
Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, Glycol dimercaptoacetate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 210.27 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.
