5-(4-Methoxyphenyl)-4-(p-tolyl)-4H-1,2,4-triazole-3-thiol CAS 5679-72-1

Description

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

CATO supplies 5-(4-Methoxyphenyl)-4-(p-tolyl)-4H-1,2,4-triazole-3-thiol (CAS 5679-72-1), a certified reference material (molecular formula C13H13N5O2, MW 271.27 g/mol) for analytical method development and quality control.

5-(4-Methoxyphenyl)-4-(p-tolyl)-4H-1,2,4-triazole-3-thiol (C13H13N5O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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), 5-(4-Methoxyphenyl)-4-(p-tolyl)-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.
