Description
CATO supplies 4,4'-(5-Fluorobenzo[c][1,2,5]thiadiazole-4,7-diyl)bis(N,N-diphenylaniline) (CAS 2133835-91-1), a certified reference material (molecular formula C42H29FN4S, MW 640.77 g/mol) for analytical method development and quality control.
The molecular framework of 4,4'-(5-Fluorobenzo[c][1,2,5]thiadiazole-4,7-diyl)bis(N,N-diphenylaniline) (C42H29FN4S) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, 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).
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 4,4'-(5-Fluorobenzo[c][1,2,5]thiadiazole-4,7-diyl)bis(N,N-diphenylaniline) 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.
