Chemical Structure

8-Methyl-2H-pyrazolo[3,4-b]quinolin-3-amine CAS 351357-40-9 chemical structure

Description

Based on its molecular formula C11H10N4, 8-Methyl-2H-pyrazolo[3,4-b]quinolin-3-amine contains a nitrogen-containing heterocyclic scaffold, a nitrile group; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 198.22 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

8-Methyl-2H-pyrazolo[3,4-b]quinolin-3-amine (CAS 351357-40-9), molecular formula C11H10N4 and molecular weight 198.22 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.
