CATO supplies N-((1-(2,2-Difluoroethyl)-1H-pyrazol-4-yl)methyl)-1-(2-fluoroethyl)-3-methyl-1H-pyrazol-4-amine hydrochloride (CAS 1856054-85-7), a certified reference material (molecular formula C12H16F3N5HCl, MW 323.75 g/mol) for analytical method development and quality control.
The molecular framework of N-((1-(2,2-Difluoroethyl)-1H-pyrazol-4-yl)methyl)-1-(2-fluoroethyl)-3-methyl-1H-pyrazol-4-amine hydrochloride (C12H16F3N5HCl) 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. 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).
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.
