Description

As a certified reference material (CRM), 5-(4-Hydroxy-3-methoxyphenyl)-4-(p-tolyl)-2,4-dihydro-3H-1,2,4-triazole-3-thione 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.

5-(4-Hydroxy-3-methoxyphenyl)-4-(p-tolyl)-2,4-dihydro-3H-1,2,4-triazole-3-thione (CAS 122772-16-1) is a high-purity analytical reference standard with the molecular formula C16H15N3O2S and a molecular weight of 313.37 g/mol.

5-(4-Hydroxy-3-methoxyphenyl)-4-(p-tolyl)-2,4-dihydro-3H-1,2,4-triazole-3-thione (C16H15N3O2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone 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.
