2-(2-Bromo-3-methoxyphenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (CAS 2018346-47-7), molecular formula C13H18BBrO3 and molecular weight 313.00 g/mol, is a CATO reference standard with documented purity and traceability.
2-(2-Bromo-3-methoxyphenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (C13H18BBrO3) 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, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
