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-(3-Fluorophenyl)-5-phenyl-1H-pyrazole (CAS 1269294-32-7), a certified reference material (molecular formula C15H11FN2, MW 238.26 g/mol) for analytical method development and quality control.
The molecular framework of 1-(3-Fluorophenyl)-5-phenyl-1H-pyrazole (C15H11FN2) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, 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. 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-(3-Fluorophenyl)-5-phenyl-1H-pyrazole 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.
