Chemical Structure
Description
The occurrence of 4-((Anthracen-9-ylmethylene)amino)-3-(2-methoxyphenyl)-1H-1,2,4-triazole-5(4H)-thione is closely related to a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4-((Anthracen-9-ylmethylene)amino)-3-(2-methoxyphenyl)-1H-1,2,4-triazole-5(4H)-thione (CAS 478256-55-2), molecular formula C24H18N4OS and molecular weight 410.49 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-((Anthracen-9-ylmethylene)amino)-3-(2-methoxyphenyl)-1H-1,2,4-triazole-5(4H)-thione (C24H18N4OS) 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
