4-Isopropyl-5-(pyridin-4-yl)-4H-1,2,4-triazole-3-thiol CAS 90871-43-5

Description

The occurrence of 4-Isopropyl-5-(pyridin-4-yl)-4H-1,2,4-triazole-3-thiol is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

4-Isopropyl-5-(pyridin-4-yl)-4H-1,2,4-triazole-3-thiol (CAS 90871-43-5), molecular formula C10H12N4S and molecular weight 220.29 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 4-Isopropyl-5-(pyridin-4-yl)-4H-1,2,4-triazole-3-thiol (C10H12N4S) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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), 4-Isopropyl-5-(pyridin-4-yl)-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.
