(3E)-5-Chloro-3-[2-(2,4,6-trichlorophenyl)hydrazin-1-ylidene]-1-{[3-(trifluoromethyl)phenyl]methyl}-2,3-dihydro-1H-indol-2-one CAS 303984-82-9 chemical structure

Description

The occurrence of (3E)-5-Chloro-3-[2-(2,4,6-trichlorophenyl)hydrazin-1-ylidene]-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.

(3E)-5-Chloro-3-[2-(2,4,6-trichlorophenyl)hydrazin-1-ylidene]-1-{[3-(trifluoromethyl)phenyl]methyl}-2,3-dihydro-1H-indol-2-one (CAS 303984-82-9), molecular formula C22H12Cl4F3N3O and molecular weight 533.16 g/mol, is a CATO reference standard with documented purity and traceability.

(3E)-5-Chloro-3-[2-(2,4,6-trichlorophenyl)hydrazin-1-ylidene]-1-{[3-(trifluoromethyl)phenyl]methyl}-2,3-dihydro-1H-indol-2-one (C22H12Cl4F3N3O) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine 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).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
