Description
Compared with other compounds in its class, the molecular weight of 337.17 g/mol gives 4-(Benzyloxy)-3-bromo-5-methoxybenzoic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
4-(Benzyloxy)-3-bromo-5-methoxybenzoic acid (CAS 568553-88-8) is a high-purity analytical reference standard with the molecular formula C15H13BrO4 and a molecular weight of 337.17 g/mol.
4-(Benzyloxy)-3-bromo-5-methoxybenzoic 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. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 4-(Benzyloxy)-3-bromo-5-methoxybenzoic acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
