Chemical Structure
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 4-Chloro-1-(4-fluorophenyl)-N-methyl-1H-pyrazole-5-carboxamide (CAS 318949-30-3), a certified reference material (molecular formula C11H9ClFN3O, MW 253.66 g/mol) for analytical method development and quality control.
The molecular framework of 4-Chloro-1-(4-fluorophenyl)-N-methyl-1H-pyrazole-5-carboxamide (C11H9ClFN3O) 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 its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
As a certified reference material (CRM), 4-Chloro-1-(4-fluorophenyl)-N-methyl-1H-pyrazole-5-carboxamide 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.
