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 4,4'-(Chloro(phenyl)methylene)bis(fluorobenzene).
CATO supplies 4,4'-(Chloro(phenyl)methylene)bis(fluorobenzene) (CAS 379-54-4), a certified reference material (molecular formula C19H13ClF2, MW 314.76 g/mol) for analytical method development and quality control.
The molecular framework of 4,4'-(Chloro(phenyl)methylene)bis(fluorobenzene) (C19H13ClF2) 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 4,4'-(Chloro(phenyl)methylene)bis(fluorobenzene) 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.
