N-((5-Fluoro-1,3-dimethyl-1H-pyrazol-4-yl)methyl)-1-(2-fluoroethyl)-4-methyl-1H-pyrazol-5-amine hydrochloride CAS 1856029-57-6 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including N-((5-Fluoro-1,3-dimethyl-1H-pyrazol-4-yl)methyl)-1-(2-fluoroethyl)-4-methyl-1H-pyrazol-5-amine hydrochloride.

CATO supplies N-((5-Fluoro-1,3-dimethyl-1H-pyrazol-4-yl)methyl)-1-(2-fluoroethyl)-4-methyl-1H-pyrazol-5-amine hydrochloride (CAS 1856029-57-6), a certified reference material (molecular formula C12H17F2N5HCl, MW 305.76 g/mol) for analytical method development and quality control.

Based on its molecular formula C12H17F2N5HCl, N-((5-Fluoro-1,3-dimethyl-1H-pyrazol-4-yl)methyl)-1-(2-fluoroethyl)-4-methyl-1H-pyrazol-5-amine hydrochloride contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 305.76 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.

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.
