5-(2,4-Dichlorophenyl)-4-(2-methylphenyl)-4h-1,2,4-triazole-3-thiol CAS 93677-85-1

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-(2,4-Dichlorophenyl)-4-(2-methylphenyl)-4h-1,2,4-triazole-3-thiol.

5-(2,4-Dichlorophenyl)-4-(2-methylphenyl)-4h-1,2,4-triazole-3-thiol (CAS 93677-85-1), molecular formula C15H11Cl2N3S and molecular weight 336.24 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 5-(2,4-Dichlorophenyl)-4-(2-methylphenyl)-4h-1,2,4-triazole-3-thiol (C15H11Cl2N3S) 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 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).

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), 5-(2,4-Dichlorophenyl)-4-(2-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.
