Chemical Structure
Description
2-(Chrysen-3-yl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (C24H23BO2) 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
2-(Chrysen-3-yl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (CAS 1593236-00-0), molecular formula C24H23BO2 and molecular weight 354.25 g/mol, is a CATO reference standard with documented purity and traceability.
