Chemical Structure

Isopropyl (R,Z)-7-(3-((tert-butyldimethylsilyl)oxy)-5-oxocyclopent-1-en-1-yl)hept-5-enoate CAS 474944-36-0 chemical structure

Description

Isopropyl (R,Z)-7-(3-((tert-butyldimethylsilyl)oxy)-5-oxocyclopent-1-en-1-yl)hept-5-enoate (C21H36O4Si) 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).
