Description
CATO manufactures 4,4'-(1,2-Diphenylethene-1,2-diyl)dianiline 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.
CATO supplies 4,4'-(1,2-Diphenylethene-1,2-diyl)dianiline (CAS 99094-20-9), a certified reference material (molecular formula C26H22N2, MW 362.47 g/mol) for analytical method development and quality control.
The molecular framework of 4,4'-(1,2-Diphenylethene-1,2-diyl)dianiline (C26H22N2) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group. 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.
