Chemical Structure
Description
4-((3-(2-Methoxyphenyl)allylidene)amino)-3-(m-tolyl)-1H-1,2,4-triazole-5(4H)-thione (CAS 478256-17-6) is a high-purity analytical reference standard with the molecular formula C19H18N4OS and a molecular weight of 350.44 g/mol.
The molecular framework of 4-((3-(2-Methoxyphenyl)allylidene)amino)-3-(m-tolyl)-1H-1,2,4-triazole-5(4H)-thione (C19H18N4OS) is characterized by a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
