1,1-Bis(4-chlorophenyl)-2-[(2-chlorophenyl)sulfanyl]ethan-1-ol (CAS 252026-72-5) is a high-purity analytical reference standard with the molecular formula C20H15Cl3OS and a molecular weight of 409.76 g/mol.
The molecular framework of 1,1-Bis(4-chlorophenyl)-2-[(2-chlorophenyl)sulfanyl]ethan-1-ol (C20H15Cl3OS) 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
