Chemical Structure
Description
As a certified reference material (CRM), 5-Bromo-2-(3-fluorophenyl)pyridazin-3(2h)-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.
5-Bromo-2-(3-fluorophenyl)pyridazin-3(2h)-one (CAS 2090941-95-8), molecular formula C10H6BrFN2O and molecular weight 269.07 g/mol, is a CATO reference standard with documented purity and traceability.
5-Bromo-2-(3-fluorophenyl)pyridazin-3(2h)-one (C10H6BrFN2O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/bromine 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
