Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
3-(2,6-difluorophenyl)-1-methyl-1H-1,2,4-triazol-5-amine hydrobromide (CAS 1909327-90-7) is a high-purity analytical reference standard with the molecular formula C9H8F2N4HBr and a molecular weight of 291.10 g/mol.
3-(2,6-difluorophenyl)-1-methyl-1H-1,2,4-triazol-5-amine hydrobromide (C9H8F2N4HBr) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/bromine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
