3-(2-Chlorophenyl)-4-(((3-methylthiophen-2-yl)methylene)amino)-1H-1,2,4-triazole-5(4H)-thione CAS 478253-87-1

Description

3-(2-Chlorophenyl)-4-(((3-methylthiophen-2-yl)methylene)amino)-1H-1,2,4-triazole-5(4H)-thione (CAS 478253-87-1), molecular formula C14H11ClN4S2 and molecular weight 334.85 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, chlorine substitution, 3-(2-Chlorophenyl)-4-(((3-methylthiophen-2-yl)methylene)amino)-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 334.85 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), 3-(2-Chlorophenyl)-4-(((3-methylthiophen-2-yl)methylene)amino)-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.
