Chemical Structure
Description
1-(2-Fluoroethyl)-N-((1-isopropyl-1H-pyrazol-4-yl)methyl)-3-methyl-1H-pyrazol-4-amine hydrochloride (CAS 1856040-89-5), molecular formula C13H20FN5HCl and molecular weight 301.79 g/mol, is a CATO reference standard with documented purity and traceability.
1-(2-Fluoroethyl)-N-((1-isopropyl-1H-pyrazol-4-yl)methyl)-3-methyl-1H-pyrazol-4-amine hydrochloride (C13H20FN5HCl) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
