N-((1,4-Dimethyl-1H-pyrazol-5-yl)methyl)-1-(2-fluoroethyl)-4-methyl-1H-pyrazol-3-amine hydrochloride (CAS 1856074-85-5), molecular formula C12H18FN5HCl and molecular weight 287.77 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of N-((1,4-Dimethyl-1H-pyrazol-5-yl)methyl)-1-(2-fluoroethyl)-4-methyl-1H-pyrazol-3-amine hydrochloride (C12H18FN5HCl) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/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.
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.
