Chemical Structure
Description
1,3,2-Dioxaborolane, 2-[6,7-difluoro-3-(methoxymethoxy)-8-[2-[tris(1-methylethyl)silyl]ethynyl]-1-naphthalenyl]-4,4,5,5-tetramethyl- (C29H41BF2O4Si) contains a steroid core, a hydroxyl group, an ether linkage, fluorine 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
