4-Phenyl-3-[(4-phenyl-5-sulfanylidene-4,5-dihydro-1H-1,2,4-triazol-3-yl)methyl]-4,5-dihydro-1H-1,2,4-triazole-5-thione CAS 21776-79-4

Description

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.

4-Phenyl-3-[(4-phenyl-5-sulfanylidene-4,5-dihydro-1H-1,2,4-triazol-3-yl)methyl]-4,5-dihydro-1H-1,2,4-triazole-5-thione (CAS 21776-79-4) is a high-purity analytical reference standard with the molecular formula C17H14N6S2 and a molecular weight of 366.46 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, 4-Phenyl-3-[(4-phenyl-5-sulfanylidene-4,5-dihydro-1H-1,2,4-triazol-3-yl)methyl]-4,5-dihydro-1H-1,2,4-triazole-5-thione is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 366.46 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
