Chemical Structure
Description
1H-Pyrazolo[3,4-b]pyridin-3-amine,-7-oxide (CAS 1198475-27-2) is a high-purity analytical reference standard with the molecular formula C6H6N4O and a molecular weight of 150.14 g/mol.
1H-Pyrazolo[3,4-b]pyridin-3-amine,-7-oxide (C6H6N4O) contains an amide group, a hydroxyl group, an ether linkage, an aromatic ring system. Its physicochemical properties are representative of its class; 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.
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.
