Description
As a certified reference material (CRM), 2-[(4-Fluorophenyl)sulfanyl]-1,1-diphenyl-1-ethanol 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-Fluorophenyl)sulfanyl]-1,1-diphenyl-1-ethanol (CAS 251307-35-4), a certified reference material (molecular formula C20H17FOS, MW 324.41 g/mol) for analytical method development and quality control.
2-[(4-Fluorophenyl)sulfanyl]-1,1-diphenyl-1-ethanol (C20H17FOS) contains a steroid core, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
