Chemical Structure
Description
Based on its molecular formula C12H15BrN4, 4-{5-bromo-1H-pyrazolo[3,4-b]pyridin-1-yl}-1-methylpiperidine contains a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 295.18 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
4-{5-bromo-1H-pyrazolo[3,4-b]pyridin-1-yl}-1-methylpiperidine (CAS 1016850-95-5), molecular formula C12H15BrN4 and molecular weight 295.18 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.
