Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2-Amino-4H-benzo[4,5]imidazo[1,2-b]pyrazole-3-carbonitrile (CAS 158591-06-1) is a high-purity analytical reference standard with the molecular formula C10H7N5 and a molecular weight of 197.20 g/mol.
Based on its molecular formula C10H7N5, 2-Amino-4H-benzo[4,5]imidazo[1,2-b]pyrazole-3-carbonitrile contains a nitrogen-containing heterocyclic scaffold, a nitrile group; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 197.20 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.
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.
