Chemical Structure
Description
CATO supplies 4-Methyl-5-(3-methylphenyl)-4H-1,2,4-triazole-3-thiol (CAS 333313-78-3), a certified reference material (molecular formula C10H11N3S, MW 205.28 g/mol) for analytical method development and quality control.
The molecular framework of 4-Methyl-5-(3-methylphenyl)-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.
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-Methyl-5-(3-methylphenyl)-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.
