Chemical Structure
Description
tert-Butyl (trans-2-((4-bromo-2-fluorobenzyl)oxy)cyclohexyl)carbamate (C18H25BrFNO3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/bromine 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
tert-Butyl (trans-2-((4-bromo-2-fluorobenzyl)oxy)cyclohexyl)carbamate (CAS 1956385-54-8) is a high-purity analytical reference standard with the molecular formula C18H25BrFNO3 and a molecular weight of 402.30 g/mol.
