Chemical Structure

6-Bromo-5-iodonicotinic acid CAS 65799-80-6 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 327.90 g/mol gives 6-Bromo-5-iodonicotinic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

6-Bromo-5-iodonicotinic acid (CAS 65799-80-6) is a high-purity analytical reference standard with the molecular formula C6H3BrINO2 and a molecular weight of 327.90 g/mol.

6-Bromo-5-iodonicotinic acid (C6H3BrINO2) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine/iodine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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), 6-Bromo-5-iodonicotinic acid 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.
