Chemical Structure

1-Ethyl-N-((1-ethyl-5-fluoro-3-methyl-1H-pyrazol-4-yl)methyl)-3-methyl-1H-pyrazol-5-amine hydrochloride CAS 1856098-41-3 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 301.79 g/mol gives 1-Ethyl-N-((1-ethyl-5-fluoro-3-methyl-1H-pyrazol-4-yl)methyl)-3-methyl-1H-pyrazol-5-amine hydrochloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 1-Ethyl-N-((1-ethyl-5-fluoro-3-methyl-1H-pyrazol-4-yl)methyl)-3-methyl-1H-pyrazol-5-amine hydrochloride (CAS 1856098-41-3), a certified reference material (molecular formula C13H20FN5HCl, MW 301.79 g/mol) for analytical method development and quality control.

The molecular framework of 1-Ethyl-N-((1-ethyl-5-fluoro-3-methyl-1H-pyrazol-4-yl)methyl)-3-methyl-1H-pyrazol-5-amine hydrochloride (C13H20FN5HCl) 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.

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.
