Chemical Structure

8-Bromodibenzo[b,d]furan-2-carboxylic acid CAS 133953-32-9 chemical structure

Description

The occurrence of 8-Bromodibenzo[b,d]furan-2-carboxylic acid is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

8-Bromodibenzo[b,d]furan-2-carboxylic acid (CAS 133953-32-9) is a high-purity analytical reference standard with the molecular formula C13H7BrO3 and a molecular weight of 291.10 g/mol.

Based on its molecular formula C13H7BrO3, 8-Bromodibenzo[b,d]furan-2-carboxylic acid contains a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 291.10 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
