Description
As a certified reference material (CRM), 1-(2,2-Difluoroethyl)-N-((3-methyl-1-propyl-1H-pyrazol-5-yl)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.
1-(2,2-Difluoroethyl)-N-((3-methyl-1-propyl-1H-pyrazol-5-yl)methyl)-1H-pyrazol-4-amine hydrochloride (CAS 1856021-66-3) is a high-purity analytical reference standard with the molecular formula C13H19F2N5HCl and a molecular weight of 319.78 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/chlorine substitution, 1-(2,2-Difluoroethyl)-N-((3-methyl-1-propyl-1H-pyrazol-5-yl)methyl)-1H-pyrazol-4-amine hydrochloride is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 319.78 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
