Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 7-Bromo-6-chloro-8-fluoro-3-nitroquinolin-4(1H)-one.
7-Bromo-6-chloro-8-fluoro-3-nitroquinolin-4(1H)-one (CAS 2349394-47-2), molecular formula C9H3BrClFN2O3 and molecular weight 321.49 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, fluorine/chlorine/bromine substitution, 7-Bromo-6-chloro-8-fluoro-3-nitroquinolin-4(1H)-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 321.49 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.
As a certified reference material (CRM), 7-Bromo-6-chloro-8-fluoro-3-nitroquinolin-4(1H)-one meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
