5-(1,5-Dimethyl-1h-pyrazol-3-yl)-4-isobutyl-4h-1,2,4-triazole-3-thiol CAS 512810-96-7

Description

The molecular framework of 5-(1,5-Dimethyl-1h-pyrazol-3-yl)-4-isobutyl-4h-1,2,4-triazole-3-thiol (C11H17N5S) 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).

5-(1,5-Dimethyl-1h-pyrazol-3-yl)-4-isobutyl-4h-1,2,4-triazole-3-thiol (CAS 512810-96-7), molecular formula C11H17N5S and molecular weight 251.35 g/mol, is a CATO reference standard with documented purity and traceability.

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), 5-(1,5-Dimethyl-1h-pyrazol-3-yl)-4-isobutyl-4h-1,2,4-triazole-3-thiol 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.
