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.
4-(2-Bromo-6-chloroacridin-9-yl)-N,N-dimethylaniline (CAS 7497-58-7), molecular formula C21H16BrClN2 and molecular weight 411.72 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine/bromine substitution, 4-(2-Bromo-6-chloroacridin-9-yl)-N,N-dimethylaniline is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 411.72 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
