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.
N-(2,5-difluorobenzyl)-1-methyl-1H-pyrazol-3-amine hydrochloride (CAS 1856046-69-9) is a high-purity analytical reference standard with the molecular formula C11H11F2N3HCl and a molecular weight of 259.68 g/mol.
Based on its molecular formula C11H11F2N3HCl, N-(2,5-difluorobenzyl)-1-methyl-1H-pyrazol-3-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 259.68 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).
As a certified reference material (CRM), N-(2,5-difluorobenzyl)-1-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.
