Description
CATO supplies 4-(Difluoro(3,4,5-trifluorophenoxy)methyl)-2',3,5-trifluoro-4''-propyl-1,1':4',1''-terphenyl (CAS 303186-36-9), a certified reference material (molecular formula C28H18F8O, MW 522.43 g/mol) for analytical method development and quality control.
The molecular framework of 4-(Difluoro(3,4,5-trifluorophenoxy)methyl)-2',3,5-trifluoro-4''-propyl-1,1':4',1''-terphenyl (C28H18F8O) 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. 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.
CATO manufactures 4-(Difluoro(3,4,5-trifluorophenoxy)methyl)-2',3,5-trifluoro-4''-propyl-1,1':4',1''-terphenyl 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.
