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-[2-(4-Fluorophenoxy)ethyl]-1H-pyrazol-4-amine (CAS 1240570-48-2), a certified reference material (molecular formula C11H12FN3O, MW 221.23 g/mol) for analytical method development and quality control.
The molecular framework of 1-[2-(4-Fluorophenoxy)ethyl]-1H-pyrazol-4-amine (C11H12FN3O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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.
As a certified reference material (CRM), 1-[2-(4-Fluorophenoxy)ethyl]-1H-pyrazol-4-amine 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.
