(3-((tert-Butyldiphenylsilyl)oxy)phenyl)boronic acid (C22H25BO3Si) contains a steroid core, a hydroxyl group, an ether linkage. 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-((tert-Butyldiphenylsilyl)oxy)phenyl)boronic acid (CAS 855779-05-4), molecular formula C22H25BO3Si and molecular weight 376.33 g/mol, is a CATO reference standard with documented purity and traceability.
