2-((4-Chlorobenzyl)sulfinyl)-1,1-bis(4-chlorophenyl)ethanol CAS 252026-70-3

Description

The occurrence of 2-((4-Chlorobenzyl)sulfinyl)-1,1-bis(4-chlorophenyl)ethanol is closely related to a steroid core, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2-((4-Chlorobenzyl)sulfinyl)-1,1-bis(4-chlorophenyl)ethanol (CAS 252026-70-3), molecular formula C21H17Cl3O2S and molecular weight 439.78 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a steroid core, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution, 2-((4-Chlorobenzyl)sulfinyl)-1,1-bis(4-chlorophenyl)ethanol is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 439.78 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.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
