4,6-Bis(4-fluorophenyl)-2-methyl-5-(pyridin-4-yl)-2H-pyrazolo[3,4-b]pyridine CAS 755753-89-0

Description

Compared with other compounds in its class, the molecular weight of 398.41 g/mol gives 4,6-Bis(4-fluorophenyl)-2-methyl-5-(pyridin-4-yl)-2H-pyrazolo[3,4-b]pyridine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

4,6-Bis(4-fluorophenyl)-2-methyl-5-(pyridin-4-yl)-2H-pyrazolo[3,4-b]pyridine (CAS 755753-89-0) is a high-purity analytical reference standard with the molecular formula C24H16F2N4 and a molecular weight of 398.41 g/mol.

Structurally, 4,6-Bis(4-fluorophenyl)-2-methyl-5-(pyridin-4-yl)-2H-pyrazolo[3,4-b]pyridine (C24H16F2N4) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 18.0, corresponding to approximately 18 ring(s) or double-bond equivalent(s). With a molecular weight of 398.41 g/mol, it falls into the moderately-high-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
