Chemical Structure
Description
Betamethasone-17,21-Dipropionate (C28H37FO7) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, a polycyclic aromatic 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).
Betamethasone-17,21-Dipropionate (CAS 5593-20-4), molecular formula C28H37FO7 and molecular weight 504.59 g/mol, is a CATO reference standard with documented purity and traceability.
