Chemical Structure
Description
The occurrence of N-Butyl-1-(2,2-difluoroethyl)-1H-pyrazol-4-amine hydrochloride is closely related to a nitrile group, fluorine/chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
N-Butyl-1-(2,2-difluoroethyl)-1H-pyrazol-4-amine hydrochloride (CAS 1856097-64-7), molecular formula C9H15F2N3HCl and molecular weight 239.69 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of N-Butyl-1-(2,2-difluoroethyl)-1H-pyrazol-4-amine hydrochloride (C9H15F2N3HCl) is characterized by 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.
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.
