4-(((5-Methylthiophen-2-yl)methylene)amino)-3-(m-tolyl)-1H-1,2,4-triazole-5(4H)-thione CAS 478256-24-5

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

4-(((5-Methylthiophen-2-yl)methylene)amino)-3-(m-tolyl)-1H-1,2,4-triazole-5(4H)-thione (CAS 478256-24-5), molecular formula C15H14N4S2 and molecular weight 314.43 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, 4-(((5-Methylthiophen-2-yl)methylene)amino)-3-(m-tolyl)-1H-1,2,4-triazole-5(4H)-thione is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 314.43 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

As a certified reference material (CRM), 4-(((5-Methylthiophen-2-yl)methylene)amino)-3-(m-tolyl)-1H-1,2,4-triazole-5(4H)-thione meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
