1-Ethyl-N-((1-ethyl-5-fluoro-3-methyl-1H-pyrazol-4-yl)methyl)-3-methyl-1H-pyrazol-4-amine hydrochloride CAS 1856039-50-3 chemical structure

Description

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.

CATO supplies 1-Ethyl-N-((1-ethyl-5-fluoro-3-methyl-1H-pyrazol-4-yl)methyl)-3-methyl-1H-pyrazol-4-amine hydrochloride (CAS 1856039-50-3), a certified reference material (molecular formula C13H20FN5HCl, MW 301.79 g/mol) for analytical method development and quality control.

Based on its molecular formula C13H20FN5HCl, 1-Ethyl-N-((1-ethyl-5-fluoro-3-methyl-1H-pyrazol-4-yl)methyl)-3-methyl-1H-pyrazol-4-amine hydrochloride contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 301.79 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

As a certified reference material (CRM), 1-Ethyl-N-((1-ethyl-5-fluoro-3-methyl-1H-pyrazol-4-yl)methyl)-3-methyl-1H-pyrazol-4-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.
