3-Bromo-2-(4-fluorophenyl)-6-(trifluoromethyl)pyrazolo[1,5-a]pyridine CAS 267235-95-0

Description

3-Bromo-2-(4-fluorophenyl)-6-(trifluoromethyl)pyrazolo[1,5-a]pyridine (C14H7BrF4N2) 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.

3-Bromo-2-(4-fluorophenyl)-6-(trifluoromethyl)pyrazolo[1,5-a]pyridine (CAS 267235-95-0) is a high-purity analytical reference standard with the molecular formula C14H7BrF4N2 and a molecular weight of 359.12 g/mol.

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.
