2-(4-Isobutylpiperazin-1-yl)-9-(4-methylphenyl)-5,6,7,9-tetrahydropyrazolo[3,4-b]pyrimido[4,5-d]azepine CAS 1171156-59-4

Description

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.

CATO supplies 2-(4-Isobutylpiperazin-1-yl)-9-(4-methylphenyl)-5,6,7,9-tetrahydropyrazolo[3,4-b]pyrimido[4,5-d]azepine (CAS 1171156-59-4), a certified reference material (molecular formula C24H31N7, MW 417.55 g/mol) for analytical method development and quality control.

Based on its molecular formula C24H31N7, 2-(4-Isobutylpiperazin-1-yl)-9-(4-methylphenyl)-5,6,7,9-tetrahydropyrazolo[3,4-b]pyrimido[4,5-d]azepine contains a nitrogen-containing heterocyclic scaffold, a nitrile group; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 417.55 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
