N1-((1-(2,2-Difluoroethyl)-5-methyl-1H-pyrazol-4-yl)methyl)-N3,N3-diethylpropane-1,3-diamine dihydrochloride CAS 1856082-77-3

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.

N1-((1-(2,2-Difluoroethyl)-5-methyl-1H-pyrazol-4-yl)methyl)-N3,N3-diethylpropane-1,3-diamine dihydrochloride (CAS 1856082-77-3) is a high-purity analytical reference standard with the molecular formula C14H26F2N4HCl and a molecular weight of 324.84 g/mol.

The molecular framework of N1-((1-(2,2-Difluoroethyl)-5-methyl-1H-pyrazol-4-yl)methyl)-N3,N3-diethylpropane-1,3-diamine dihydrochloride (C14H26F2N4HCl) is characterized by a nitrile group, fluorine/chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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.

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.
