Chemical Structure
Description
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.
1-(1-Ethyl-1H-pyrazol-3-yl)-N-((1-isopropyl-1H-pyrazol-3-yl)methyl)methanamine hydrochloride (CAS 1856058-89-3) is a high-purity analytical reference standard with the molecular formula C13H21N5HCl and a molecular weight of 283.80 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution, 1-(1-Ethyl-1H-pyrazol-3-yl)-N-((1-isopropyl-1H-pyrazol-3-yl)methyl)methanamine hydrochloride is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 283.80 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
