Chemical Structure
Description
3,6-Dibromo-2,7-bis(hexyloxy)-1,8-naphthyridine (C20H28Br2N2O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution. 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
3,6-Dibromo-2,7-bis(hexyloxy)-1,8-naphthyridine (CAS 1263094-79-6), molecular formula C20H28Br2N2O2 and molecular weight 488.26 g/mol, is a CATO reference standard with documented purity and traceability.
