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 2-((4-Chlorobenzyl)thio)-1,1-bis(4-chlorophenyl)ethanol (CAS 252026-68-9), a certified reference material (molecular formula C21H17Cl3OS, MW 423.78 g/mol) for analytical method development and quality control.
The molecular framework of 2-((4-Chlorobenzyl)thio)-1,1-bis(4-chlorophenyl)ethanol (C21H17Cl3OS) is characterized by a steroid core, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
