Chemical Structure
Description
The occurrence of (3Z)-3-{[(2,4-dichlorophenyl)methoxy]imino}-1-{[3-(trifluoromethyl)phenyl]methyl}-2,3-dihydro-1H-indol-2-one is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(3Z)-3-{[(2,4-dichlorophenyl)methoxy]imino}-1-{[3-(trifluoromethyl)phenyl]methyl}-2,3-dihydro-1H-indol-2-one (CAS 477853-37-5), molecular formula C23H15Cl2F3N2O2 and molecular weight 479.28 g/mol, is a CATO reference standard with documented purity and traceability.
(3Z)-3-{[(2,4-dichlorophenyl)methoxy]imino}-1-{[3-(trifluoromethyl)phenyl]methyl}-2,3-dihydro-1H-indol-2-one (C23H15Cl2F3N2O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine 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.
As a certified reference material (CRM), (3Z)-3-{[(2,4-dichlorophenyl)methoxy]imino}-1-{[3-(trifluoromethyl)phenyl]methyl}-2,3-dihydro-1H-indol-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.
