Compared with other compounds in its class, the molecular weight of 399.45 g/mol gives 2,4,6-Tris(4-hydrazinylphenyl)-1,3,5-triazine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2,4,6-Tris(4-hydrazinylphenyl)-1,3,5-triazine (CAS 804548-56-9), molecular formula C21H21N9 and molecular weight 399.45 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2,4,6-Tris(4-hydrazinylphenyl)-1,3,5-triazine (C21H21N9) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
