Chemical Structure
Description
As a certified reference material (CRM), 1-(4-Fluorophenyl)-5-methyl-4-(pyridin-2-yl)-1,2-dihydro-3H-pyrazol-3-one 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.
CATO supplies 1-(4-Fluorophenyl)-5-methyl-4-(pyridin-2-yl)-1,2-dihydro-3H-pyrazol-3-one (CAS 956796-43-3), a certified reference material (molecular formula C15H12FN3O, MW 269.27 g/mol) for analytical method development and quality control.
1-(4-Fluorophenyl)-5-methyl-4-(pyridin-2-yl)-1,2-dihydro-3H-pyrazol-3-one (C15H12FN3O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
