Chemical Structure

1,1-Bis(4-chlorophenyl)-2-[(4-methoxyphenyl)sulfanyl]ethan-1-ol CAS 337919-98-9 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 1,1-Bis(4-chlorophenyl)-2-[(4-methoxyphenyl)sulfanyl]ethan-1-ol (CAS 337919-98-9), a certified reference material (molecular formula C21H18Cl2O2S, MW 405.34 g/mol) for analytical method development and quality control.

Owing to a steroid core, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution, 1,1-Bis(4-chlorophenyl)-2-[(4-methoxyphenyl)sulfanyl]ethan-1-ol is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 405.34 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
