Chemical Structure

4-(1-Phenylethyl)-4h-1,2,4-triazole-3-thiol CAS 642075-26-1 chemical structure

Description

As a certified reference material (CRM), 4-(1-Phenylethyl)-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.

4-(1-Phenylethyl)-4h-1,2,4-triazole-3-thiol (CAS 642075-26-1), molecular formula C10H11N3S and molecular weight 205.28 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 4-(1-Phenylethyl)-4h-1,2,4-triazole-3-thiol (C10H11N3S) 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
