5-Fluoro-9-oxo-9,10-dihydroacridine-4-carboxylic acid (CAS 98370-46-8), molecular formula C14H8FNO3 and molecular weight 257.22 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 5-Fluoro-9-oxo-9,10-dihydroacridine-4-carboxylic acid (C14H8FNO3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 257.22 g/mol, it falls into the medium-molecular-weight range. 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.
