8-Bromo-6-fluoro-4-oxo-1,4-dihydroquinoline-2-carboxylic acid CAS 1339156-37-4

Description

Compared with other compounds in its class, the molecular weight of 286.05 g/mol gives 8-Bromo-6-fluoro-4-oxo-1,4-dihydroquinoline-2-carboxylic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

8-Bromo-6-fluoro-4-oxo-1,4-dihydroquinoline-2-carboxylic acid (CAS 1339156-37-4), molecular formula C10H5BrFNO3 and molecular weight 286.05 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C10H5BrFNO3, 8-Bromo-6-fluoro-4-oxo-1,4-dihydroquinoline-2-carboxylic acid contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 286.05 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
