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-Bromo-2-(trifluoromethyl)isonicotinonitrile (CAS 1807005-92-0), molecular formula C7H2BrF3N2 and molecular weight 251.00 g/mol, is a CATO reference standard with documented purity and traceability.
3-Bromo-2-(trifluoromethyl)isonicotinonitrile (C7H2BrF3N2) contains a nitrile group, fluorine/bromine substitution, an aromatic ring system. 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.
