Chemical Structure
Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 4''-Ethyl-2'-fluoro-4-pentyl-1,1':4',1''-terphenyl (CAS 95759-59-4), a certified reference material (molecular formula C25H27F, MW 346.48 g/mol) for analytical method development and quality control.
The molecular framework of 4''-Ethyl-2'-fluoro-4-pentyl-1,1':4',1''-terphenyl (C25H27F) is characterized by fluorine 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.
CATO manufactures 4''-Ethyl-2'-fluoro-4-pentyl-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.
