Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
1-(1-(2,2-Difluoroethyl)-1H-pyrazol-3-yl)-N-((1-ethyl-1H-pyrazol-5-yl)methyl)methanamine hydrochloride (CAS 1856024-71-9) is a high-purity analytical reference standard with the molecular formula C12H17F2N5HCl and a molecular weight of 305.76 g/mol.
The molecular framework of 1-(1-(2,2-Difluoroethyl)-1H-pyrazol-3-yl)-N-((1-ethyl-1H-pyrazol-5-yl)methyl)methanamine hydrochloride (C12H17F2N5HCl) 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. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
