Chemical Structure

3-Bromo-4-fluorophthalic acid CAS 2828433-78-7 chemical structure

Description

The occurrence of 3-Bromo-4-fluorophthalic acid is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

3-Bromo-4-fluorophthalic acid (CAS 2828433-78-7) is a high-purity analytical reference standard with the molecular formula C8H4BrFO4 and a molecular weight of 263.02 g/mol.

3-Bromo-4-fluorophthalic acid (C8H4BrFO4) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/bromine substitution, an aromatic ring system. It is notably hygroscopic, 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), 3-Bromo-4-fluorophthalic 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.
