Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (3E)-5-Chloro-3-{2-[2,6-dichloro-4-(trifluoromethyl)phenyl]hydrazin-1-ylidene}-1-{[3-(trifluoromethyl)phenyl]methyl}-2,3-dihydro-1H-indol-2-one.
(3E)-5-Chloro-3-{2-[2,6-dichloro-4-(trifluoromethyl)phenyl]hydrazin-1-ylidene}-1-{[3-(trifluoromethyl)phenyl]methyl}-2,3-dihydro-1H-indol-2-one (CAS 303984-79-4) is a high-purity analytical reference standard with the molecular formula C23H12Cl3F6N3O and a molecular weight of 566.71 g/mol.
(3E)-5-Chloro-3-{2-[2,6-dichloro-4-(trifluoromethyl)phenyl]hydrazin-1-ylidene}-1-{[3-(trifluoromethyl)phenyl]methyl}-2,3-dihydro-1H-indol-2-one (C23H12Cl3F6N3O) 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
