Chemical Structure
Description
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.
1-(1-Ethyl-5-fluoro-3-methyl-1H-pyrazol-4-yl)-N-((1-(2-fluoroethyl)-1H-pyrazol-3-yl)methyl)methanamine hydrochloride (CAS 1856089-20-7), molecular formula C13H19F2N5HCl and molecular weight 319.78 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1-(1-Ethyl-5-fluoro-3-methyl-1H-pyrazol-4-yl)-N-((1-(2-fluoroethyl)-1H-pyrazol-3-yl)methyl)methanamine hydrochloride (C13H19F2N5HCl) 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
