4-Bromo-7,8-dichloro-2-phenylquinoline CAS 1189107-14-9

Description

Compared with other compounds in its class, the molecular weight of 353.04 g/mol gives 4-Bromo-7,8-dichloro-2-phenylquinoline distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

4-Bromo-7,8-dichloro-2-phenylquinoline (CAS 1189107-14-9), molecular formula C15H8BrCl2N and molecular weight 353.04 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 4-Bromo-7,8-dichloro-2-phenylquinoline (C15H8BrCl2N) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine/bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 353.04 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
