Description
CATO supplies 2-(3-(((1-(2,2-Difluoroethyl)-5-methyl-1H-pyrazol-4-yl)methyl)amino)-1H-pyrazol-1-yl)ethan-1-ol hydrochloride (CAS 1855943-74-6), a certified reference material (molecular formula C12H17F2N5OHCl, MW 321.76 g/mol) for analytical method development and quality control.
The molecular framework of 2-(3-(((1-(2,2-Difluoroethyl)-5-methyl-1H-pyrazol-4-yl)methyl)amino)-1H-pyrazol-1-yl)ethan-1-ol hydrochloride (C12H17F2N5OHCl) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 2-(3-(((1-(2,2-Difluoroethyl)-5-methyl-1H-pyrazol-4-yl)methyl)amino)-1H-pyrazol-1-yl)ethan-1-ol 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.
