Chemical Structure

2,5-Dibromo-3,6-difluorobenzoic acid CAS 1263376-61-9 chemical structure

Description

The occurrence of 2,5-Dibromo-3,6-difluorobenzoic 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.

CATO supplies 2,5-Dibromo-3,6-difluorobenzoic acid (CAS 1263376-61-9), a certified reference material (molecular formula C7H2Br2F2O2, MW 315.89 g/mol) for analytical method development and quality control.

2,5-Dibromo-3,6-difluorobenzoic acid (C7H2Br2F2O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/bromine 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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), 2,5-Dibromo-3,6-difluorobenzoic 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.
