Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
3-Methyl-N-((1-methyl-1H-pyrrol-2-yl)methyl)-1-propyl-1H-pyrazol-4-amine hydrochloride (CAS 1856021-73-2) is a high-purity analytical reference standard with the molecular formula C13H20N4HCl and a molecular weight of 268.79 g/mol.
Based on its molecular formula C13H20N4HCl, 3-Methyl-N-((1-methyl-1H-pyrrol-2-yl)methyl)-1-propyl-1H-pyrazol-4-amine hydrochloride contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 268.79 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.
