2-(2,4-Difluorophenyl)-1,2-dihydrophthalazin-1-one CAS 380183-86-8

Description

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.

2-(2,4-Difluorophenyl)-1,2-dihydrophthalazin-1-one (CAS 380183-86-8), molecular formula C14H8F2N2O and molecular weight 258.22 g/mol, is a CATO reference standard with documented purity and traceability.

2-(2,4-Difluorophenyl)-1,2-dihydrophthalazin-1-one (C14H8F2N2O) 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.
