Description

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.

CATO supplies 3-(1,3-Dimethyl-1H-pyrazol-4-yl)-4-ethyl-1H-1,2,4-triazole-5(4H)-thione (CAS 512811-84-6), a certified reference material (molecular formula C9H13N5S, MW 223.30 g/mol) for analytical method development and quality control.

The molecular framework of 3-(1,3-Dimethyl-1H-pyrazol-4-yl)-4-ethyl-1H-1,2,4-triazole-5(4H)-thione (C9H13N5S) 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).

As a certified reference material (CRM), 3-(1,3-Dimethyl-1H-pyrazol-4-yl)-4-ethyl-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.
