Chemical Structure
Description
25B-NBOH HCl RM (C17H20BrNO3HCl) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine/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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
25B-NBOH HCl RM (CAS 1539266-16-4), molecular formula C17H20BrNO3HCl and molecular weight 402.71 g/mol, is a CATO reference standard with documented purity and traceability.
