Chemical Structure
Description
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine substitution, 10,12-Diphenylbenzo[c]pyrido[1,2-a][1,8]naphthyridin-13-ium tetrafluoroborate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 470.28 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).
10,12-Diphenylbenzo[c]pyrido[1,2-a][1,8]naphthyridin-13-ium tetrafluoroborate (CAS 89419-68-1), molecular formula C28H19N2BF4 and molecular weight 470.28 g/mol, is a CATO reference standard with documented purity and traceability.
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.
