1,4-Dibromo-2,5-bis(2-(2-(2-methoxyethoxy)ethoxy)ethoxy)benzene (CAS 187754-76-3) is a high-purity analytical reference standard with the molecular formula C20H32Br2O8 and a molecular weight of 560.27 g/mol.
1,4-Dibromo-2,5-bis(2-(2-(2-methoxyethoxy)ethoxy)ethoxy)benzene (C20H32Br2O8) contains a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
