Chemical Structure
Description
N,N'-(9,10-Dioxo-9,10-dihydroanthracene-2,6-diyl)dibenzamide (CAS 6470-90-2), molecular formula C15H18ClF3N2O3S and molecular weight 398.83 g/mol, is a CATO reference standard with documented purity and traceability.
N,N'-(9,10-Dioxo-9,10-dihydroanthracene-2,6-diyl)dibenzamide (C15H18ClF3N2O3S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
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.
