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.
CATO supplies 1-Ethyl-N-((1-isopropyl-1H-pyrazol-5-yl)methyl)-3-methyl-1H-pyrazol-5-amine hydrochloride (CAS 1856080-99-3), a certified reference material (molecular formula C13H21N5HCl, MW 283.80 g/mol) for analytical method development and quality control.
1-Ethyl-N-((1-isopropyl-1H-pyrazol-5-yl)methyl)-3-methyl-1H-pyrazol-5-amine hydrochloride (C13H21N5HCl) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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), 1-Ethyl-N-((1-isopropyl-1H-pyrazol-5-yl)methyl)-3-methyl-1H-pyrazol-5-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.
