Description
As a certified reference material (CRM), 4-(1H-Benzo[d][1,2,3]triazol-1-yl)-1-methylpyridin-1-ium iodide meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
4-(1H-Benzo[d][1,2,3]triazol-1-yl)-1-methylpyridin-1-ium iodide (CAS 457051-53-5) is a high-purity analytical reference standard with the molecular formula C12H11N4I and a molecular weight of 338.15 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, iodine substitution, 4-(1H-Benzo[d][1,2,3]triazol-1-yl)-1-methylpyridin-1-ium iodide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 338.15 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
