Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 1-(sec-Butyl)-N-((1-ethyl-1H-pyrazol-4-yl)methyl)-1H-pyrazol-3-amine hydrochloride (CAS 1856034-00-8), a certified reference material (molecular formula C13H21N5HCl, MW 283.80 g/mol) for analytical method development and quality control.
The molecular framework of 1-(sec-Butyl)-N-((1-ethyl-1H-pyrazol-4-yl)methyl)-1H-pyrazol-3-amine hydrochloride (C13H21N5HCl) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
As a certified reference material (CRM), 1-(sec-Butyl)-N-((1-ethyl-1H-pyrazol-4-yl)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.
