Chemical Structure
Description
As a certified reference material (CRM), 3-(3,5-dichlorophenyl)-1H-1,2,4-triazole-5-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.
CATO supplies 3-(3,5-dichlorophenyl)-1H-1,2,4-triazole-5-thiol (CAS 261511-12-0), a certified reference material (molecular formula C8H5Cl2N3S, MW 246.12 g/mol) for analytical method development and quality control.
The molecular framework of 3-(3,5-dichlorophenyl)-1H-1,2,4-triazole-5-thiol (C8H5Cl2N3S) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution. 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
