Description
CATO supplies 2-(2,4-difluorophenyl)pyridine 2-[2,4-bis(fluoranyl)phenyl]pyridine 391604-55-0 A824431 (CAS 391604-55-0), a certified reference material (molecular formula C11H19F2N, MW 203.27 g/mol) for analytical method development and quality control.
2-(2,4-difluorophenyl)pyridine 2-[2,4-bis(fluoranyl)phenyl]pyridine 391604-55-0 A824431 (C11H19F2N) contains a nitrile group, fluorine 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.
