Chemical Structure
Description
CATO supplies 3-Benzyl-2-fluoro-4-iodopyridine (CAS 655245-95-7), a certified reference material (molecular formula C12H9FIN, MW 313.11 g/mol) for analytical method development and quality control.
3-Benzyl-2-fluoro-4-iodopyridine (C12H9FIN) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/iodine 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.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
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.
