1,8-Bis(4-bromophenoxy)octane (CAS 117499-25-9), molecular formula C20H24Br2O2 and molecular weight 456.21 g/mol, is a CATO reference standard with documented purity and traceability.
1,8-Bis(4-bromophenoxy)octane (C20H24Br2O2) contains a steroid 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
