Compared with other compounds in its class, the molecular weight of 199.21 g/mol gives 4-Methyl-1,3,5-triazino[1,2-a]benzimidazol-2-amine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 4-Methyl-1,3,5-triazino[1,2-a]benzimidazol-2-amine (CAS 78650-16-5), a certified reference material (molecular formula C10H9N5, MW 199.21 g/mol) for analytical method development and quality control.
The molecular framework of 4-Methyl-1,3,5-triazino[1,2-a]benzimidazol-2-amine (C10H9N5) 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.
