Chemical Structure
Description
As a certified reference material (CRM), 5-Bromo-1-(3-fluorophenyl)-N-methyl-1H-pyrazole-4-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.
5-Bromo-1-(3-fluorophenyl)-N-methyl-1H-pyrazole-4-carboxamide (CAS 98533-44-9) is a high-purity analytical reference standard with the molecular formula C22H29F3N2O12 and a molecular weight of 570.47 g/mol.
The molecular framework of 5-Bromo-1-(3-fluorophenyl)-N-methyl-1H-pyrazole-4-carboxamide (C22H29F3N2O12) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine 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 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).
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.
