Chemical Structure
Description
As a certified reference material (CRM), 2-{[(4-chlorophenyl)methyl]sulfanyl}-1,1-bis(4-fluorophenyl)ethan-1-ol meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
CATO supplies 2-{[(4-chlorophenyl)methyl]sulfanyl}-1,1-bis(4-fluorophenyl)ethan-1-ol (CAS 303152-11-6), a certified reference material (molecular formula C21H17ClF2OS, MW 390.87 g/mol) for analytical method development and quality control.
The molecular framework of 2-{[(4-chlorophenyl)methyl]sulfanyl}-1,1-bis(4-fluorophenyl)ethan-1-ol (C21H17ClF2OS) is characterized by a steroid core, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine/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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
