Chemical Structure

7-Bromo-2-oxo-1,2-dihydroquinoline-4-carboxylic acid CAS 762260-63-9 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 268.06 g/mol gives 7-Bromo-2-oxo-1,2-dihydroquinoline-4-carboxylic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

7-Bromo-2-oxo-1,2-dihydroquinoline-4-carboxylic acid (CAS 762260-63-9), molecular formula C10H6BrNO3 and molecular weight 268.06 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution, 7-Bromo-2-oxo-1,2-dihydroquinoline-4-carboxylic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 268.06 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
