4-((1H-pyrazolo[3,4-b]pyridin-4-yl)oxy)-3-fluoroaniline CAS 1115490-85-1

Description

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution, 4-((1H-pyrazolo[3,4-b]pyridin-4-yl)oxy)-3-fluoroaniline is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 244.22 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

4-((1H-pyrazolo[3,4-b]pyridin-4-yl)oxy)-3-fluoroaniline (CAS 1115490-85-1), molecular formula C12H9FN4O and molecular weight 244.22 g/mol, is a CATO reference standard with documented purity and traceability.

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.
