Chemical Structure
Description
(E)-N'-((2E,4E)-5-Phenylpenta-2,4-dien-1-ylidene)-2-(trifluoromethyl)benzenesulfonohydrazide (CAS 2765851-43-0) is a high-purity analytical reference standard with the molecular formula C18H15F3N2O2S and a molecular weight of 380.38 g/mol.
(E)-N'-((2E,4E)-5-Phenylpenta-2,4-dien-1-ylidene)-2-(trifluoromethyl)benzenesulfonohydrazide (C18H15F3N2O2S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
