Chemical Structure
Description
The occurrence of N3-[3,5-di(trifluoromethyl)phenyl]-4,5,6,7-tetrafluoro-2-methylbenzo[b]furan-3-carboxamide is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
N3-[3,5-di(trifluoromethyl)phenyl]-4,5,6,7-tetrafluoro-2-methylbenzo[b]furan-3-carboxamide (CAS 256329-58-5) is a high-purity analytical reference standard with the molecular formula C18H7F10NO2 and a molecular weight of 459.24 g/mol.
N3-[3,5-di(trifluoromethyl)phenyl]-4,5,6,7-tetrafluoro-2-methylbenzo[b]furan-3-carboxamide (C18H7F10NO2) contains a steroid core, an amide group, 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
