2,9-Dimethylquinolino[2,3-b]acridine-7,14(5H,12H)-dione CAS 980-26-7

Description

The occurrence of 2,9-Dimethylquinolino[2,3-b]acridine-7,14(5H,12H)-dione is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2,9-Dimethylquinolino[2,3-b]acridine-7,14(5H,12H)-dione (CAS 980-26-7) is a high-purity analytical reference standard with the molecular formula C22H16N2O2 and a molecular weight of 340.37 g/mol.

2,9-Dimethylquinolino[2,3-b]acridine-7,14(5H,12H)-dione (C22H16N2O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
