Chemical Structure
Description
The molecular framework of 4-((4-(Diethylamino)benzylidene)amino)-3-(m-tolyl)-1H-1,2,4-triazole-5(4H)-thione (C20H23N5S) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, 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).
4-((4-(Diethylamino)benzylidene)amino)-3-(m-tolyl)-1H-1,2,4-triazole-5(4H)-thione (CAS 478256-08-5), molecular formula C20H23N5S and molecular weight 365.50 g/mol, is a CATO reference standard with documented purity and traceability.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
