3-(Benzylthio)-4-methyl-5-(1-phenyl-5-(1H-pyrrol-1-yl)-1H-pyrazol-4-yl)-4H-1,2,4-triazole (CAS 956741-68-7), molecular formula C23H20N6S and molecular weight 412.51 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, 3-(Benzylthio)-4-methyl-5-(1-phenyl-5-(1H-pyrrol-1-yl)-1H-pyrazol-4-yl)-4H-1,2,4-triazole is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 412.51 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
