Description
Compared with other compounds in its class, the molecular weight of 331.80 g/mol gives N-((1-Cyclopentyl-1H-pyrazol-4-yl)methyl)-1-(difluoromethyl)-3-methyl-1H-pyrazol-4-amine hydrochloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
N-((1-Cyclopentyl-1H-pyrazol-4-yl)methyl)-1-(difluoromethyl)-3-methyl-1H-pyrazol-4-amine hydrochloride (CAS 1856019-44-7), molecular formula C14H19F2N5HCl and molecular weight 331.80 g/mol, is a CATO reference standard with documented purity and traceability.
N-((1-Cyclopentyl-1H-pyrazol-4-yl)methyl)-1-(difluoromethyl)-3-methyl-1H-pyrazol-4-amine hydrochloride (C14H19F2N5HCl) 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
