Chemical Structure
Description
The occurrence of 1,1-Bis-(4-Fluorophenyl)-2,2-Dichloroethane is closely related to fluorine/chlorine substitution, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 1,1-Bis-(4-Fluorophenyl)-2,2-Dichloroethane (CAS 603-55-4), a certified reference material (molecular formula C14H10Cl2F2, MW 287.13 g/mol) for analytical method development and quality control.
The molecular framework of 1,1-Bis-(4-Fluorophenyl)-2,2-Dichloroethane (C14H10Cl2F2) is characterized by fluorine/chlorine substitution, a polycyclic aromatic system. 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.
CATO manufactures 1,1-Bis-(4-Fluorophenyl)-2,2-Dichloroethane 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.
