Chemical Structure
Description
The molecular framework of 1-(Difluoromethyl)-N-((5-fluoro-1,3-dimethyl-1H-pyrazol-4-yl)methyl)-1H-pyrazol-3-amine hydrochloride (C10H12F3N5HCl) 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.
CATO supplies 1-(Difluoromethyl)-N-((5-fluoro-1,3-dimethyl-1H-pyrazol-4-yl)methyl)-1H-pyrazol-3-amine hydrochloride (CAS 1855949-89-1), a certified reference material (molecular formula C10H12F3N5HCl, MW 295.69 g/mol) for analytical method development and quality control.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
