Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 228.84 g/mol gives (2-Bromo-4-formylphenyl)boronic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
(2-Bromo-4-formylphenyl)boronic acid (CAS 2376607-81-5), molecular formula C7H6BBrO3 and molecular weight 228.84 g/mol, is a CATO reference standard with documented purity and traceability.
(2-Bromo-4-formylphenyl)boronic acid (C7H6BBrO3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
