Chemical Structure
Description
4-Hydroxy-3-(((4-(trifluoromethyl)phenyl)imino)methyl)-2H-chromen-2-one (CAS 478077-39-3) is a high-purity analytical reference standard with the molecular formula C17H10F3NO3 and a molecular weight of 333.26 g/mol.
4-Hydroxy-3-(((4-(trifluoromethyl)phenyl)imino)methyl)-2H-chromen-2-one (C17H10F3NO3) 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.
As a certified reference material (CRM), 4-Hydroxy-3-(((4-(trifluoromethyl)phenyl)imino)methyl)-2H-chromen-2-one meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
