N-{(Z)-[4-(1H-1,2,3,4-Tetraazol-5-yl)phenyl]methylidene}-4H-1,2,4-triazol-4-amine (CAS 478039-39-3), molecular formula C10H8N8 and molecular weight 240.22 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, N-{(Z)-[4-(1H-1,2,3,4-Tetraazol-5-yl)phenyl]methylidene}-4H-1,2,4-triazol-4-amine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 240.22 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.
