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 Dimethyl 2,2'-thiobis(3-phenylpropanoate) (CAS 17277-59-7), a certified reference material (molecular formula C20H22O4S, MW 358.45 g/mol) for analytical method development and quality control.
Owing to a flavonoid core, a sulfone group, a hydroxyl group, an ether linkage, Dimethyl 2,2'-thiobis(3-phenylpropanoate) is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 358.45 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
