Chemical Structure
Description
5-Trifluoromethyl-2H-pyridazine-2-one (CAS 244268-34-6), molecular formula C5H7F3N2O and molecular weight 168.12 g/mol, is a CATO reference standard with documented purity and traceability.
5-Trifluoromethyl-2H-pyridazine-2-one (C5H7F3N2O) contains an amide group, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
As a certified reference material (CRM), 5-Trifluoromethyl-2H-pyridazine-2-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.
