CATO supplies 5-Bromo-2-(3-methyl-5-(trifluoromethyl)-1H-pyrazol-1-yl)pyridine (CAS 1187385-59-6), a certified reference material (molecular formula C10H7BrF3N3, MW 306.08 g/mol) for analytical method development and quality control.
5-Bromo-2-(3-methyl-5-(trifluoromethyl)-1H-pyrazol-1-yl)pyridine (C10H7BrF3N3) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/bromine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; 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.
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.
