135586-17-3 2-Bromo-3-benzyloxy-4-methoxybenzoic Acid 2-Bromo-4-methoxy-3-(phenylmethoxy)-benzoic Acid (CAS 135586-17-3) is a high-purity analytical reference standard with the molecular formula C15H13BrO4 and a molecular weight of 337.17 g/mol.
135586-17-3 2-Bromo-3-benzyloxy-4-methoxybenzoic Acid 2-Bromo-4-methoxy-3-(phenylmethoxy)-benzoic Acid (C15H13BrO4) contains a flavonoid core, a hydroxyl group, an ether linkage, bromine substitution. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
