Chemical Structure
Description
The molecular framework of 1-(1-Ethyl-3-methyl-1H-pyrazol-4-yl)-N-((1-isopropyl-5-methyl-1H-pyrazol-4-yl)methyl)methanamine hydrochloride (C15H25N5HCl) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
1-(1-Ethyl-3-methyl-1H-pyrazol-4-yl)-N-((1-isopropyl-5-methyl-1H-pyrazol-4-yl)methyl)methanamine hydrochloride (CAS 1856083-43-6) is a high-purity analytical reference standard with the molecular formula C15H25N5HCl and a molecular weight of 311.86 g/mol.
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.
