Description
CATO supplies 5-(3-Chloro-5-(trifluoromethyl)pyridin-2-yl)-2-(p-tolyl)-4,5,6,7-tetrahydro-2H-pyrazolo[4,3-c]pyridine (CAS 250714-13-7), a certified reference material (molecular formula C19H16ClF3N4, MW 392.81 g/mol) for analytical method development and quality control.
5-(3-Chloro-5-(trifluoromethyl)pyridin-2-yl)-2-(p-tolyl)-4,5,6,7-tetrahydro-2H-pyrazolo[4,3-c]pyridine (C19H16ClF3N4) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/chlorine 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. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
