Chemical Structure

3-Chloro-8H-quinolino[4,3,2-kl]acridine CAS 198025-90-0 chemical structure

Description

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.

3-Chloro-8H-quinolino[4,3,2-kl]acridine (CAS 198025-90-0), molecular formula C19H11ClN2 and molecular weight 302.76 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C19H11ClN2, 3-Chloro-8H-quinolino[4,3,2-kl]acridine contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 302.76 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
