Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1 4-Bis(trifluoromethyl)-1 4-diphenyl-2&.
CATO supplies 1 4-Bis(trifluoromethyl)-1 4-diphenyl-2& (CAS 247170-26-9), a certified reference material (molecular formula C18H12F6O2, MW 374.28 g/mol) for analytical method development and quality control.
The molecular framework of 1 4-Bis(trifluoromethyl)-1 4-diphenyl-2& (C18H12F6O2) is characterized by a steroid core, a hydroxyl group, an ether linkage, fluorine 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. 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.
CATO manufactures 1 4-Bis(trifluoromethyl)-1 4-diphenyl-2& under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
