Description

Compared with other compounds in its class, the molecular weight of 225.33 g/mol gives 4-Ethyl-3-(3-methylthiophen-2-yl)-1H-1,2,4-triazole-5(4H)-thione distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 4-Ethyl-3-(3-methylthiophen-2-yl)-1H-1,2,4-triazole-5(4H)-thione (CAS 777875-20-4), a certified reference material (molecular formula C9H11N3S2, MW 225.33 g/mol) for analytical method development and quality control.

The molecular framework of 4-Ethyl-3-(3-methylthiophen-2-yl)-1H-1,2,4-triazole-5(4H)-thione (C9H11N3S2) 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 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.

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