Chemical Structure
Description
(E)-({5-[(4-bromophenyl)sulfanyl]-1-methyl-3-phenyl-1H-pyrazol-4-yl}methylidene)[(4-fluorophenyl)methoxy]amine (C24H19BrFN3OS) contains a steroid core, an amide group, sulfur-containing functionality, 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; 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).
