Chemical Structure
Description
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.
(2-Bromo-3,4,5,6-tetrafluorophenyl)boronic acid (CAS 849062-35-7), molecular formula C6H2BBrF4O2 and molecular weight 272.79 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C6H2BBrF4O2, (2-Bromo-3,4,5,6-tetrafluorophenyl)boronic acid contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 272.79 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
