5-bromobenzofuran-7-carboxylic acid CAS 99517-39-2

Description

Compared with other compounds in its class, the molecular weight of 249.10 g/mol gives 5-bromobenzofuran-7-carboxylic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

5-bromobenzofuran-7-carboxylic acid (CAS 99517-39-2), molecular formula C9H13BrO3 and molecular weight 249.10 g/mol, is a CATO reference standard with documented purity and traceability.

5-bromobenzofuran-7-carboxylic acid (C9H13BrO3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), 5-bromobenzofuran-7-carboxylic 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.
