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.
(3-Bromo-6-ethoxy-2-fluorophenyl)boronic acid (CAS 1309980-98-0), molecular formula C8H9BBrFO3 and molecular weight 262.87 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C8H9BBrFO3, (3-Bromo-6-ethoxy-2-fluorophenyl)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 262.87 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.
