3-Chloro-2-{2-phenyl-2H,4H,5H,6H,7H-pyrazolo[4,3-c]pyridin-5-yl}-5-(trifluoromethyl)pyridine CAS 337919-61-6

Description

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.

CATO supplies 3-Chloro-2-{2-phenyl-2H,4H,5H,6H,7H-pyrazolo[4,3-c]pyridin-5-yl}-5-(trifluoromethyl)pyridine (CAS 337919-61-6), a certified reference material (molecular formula C18H14ClF3N4, MW 378.78 g/mol) for analytical method development and quality control.

3-Chloro-2-{2-phenyl-2H,4H,5H,6H,7H-pyrazolo[4,3-c]pyridin-5-yl}-5-(trifluoromethyl)pyridine (C18H14ClF3N4) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
