N-((1-Ethyl-3-methyl-1H-pyrazol-4-yl)methyl)-1-(2-fluoroethyl)-4-methyl-1H-pyrazol-3-amine hydrochloride CAS 1856019-72-1 chemical structure

Description

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/chlorine substitution, N-((1-Ethyl-3-methyl-1H-pyrazol-4-yl)methyl)-1-(2-fluoroethyl)-4-methyl-1H-pyrazol-3-amine hydrochloride is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 301.79 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).

CATO supplies N-((1-Ethyl-3-methyl-1H-pyrazol-4-yl)methyl)-1-(2-fluoroethyl)-4-methyl-1H-pyrazol-3-amine hydrochloride (CAS 1856019-72-1), a certified reference material (molecular formula C13H20FN5HCl, MW 301.79 g/mol) for analytical method development and quality control.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), N-((1-Ethyl-3-methyl-1H-pyrazol-4-yl)methyl)-1-(2-fluoroethyl)-4-methyl-1H-pyrazol-3-amine hydrochloride meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
