(3E)-3-[2-(3,5-Dichlorophenyl)hydrazin-1-ylidene]-1-(prop-2-en-1-yl)-2,3-dihydro-1H-indol-2-one (CAS 320422-18-2) is a high-purity analytical reference standard with the molecular formula C17H13Cl2N3O and a molecular weight of 346.21 g/mol.
(3E)-3-[2-(3,5-Dichlorophenyl)hydrazin-1-ylidene]-1-(prop-2-en-1-yl)-2,3-dihydro-1H-indol-2-one (C17H13Cl2N3O) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, 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).
CATO manufactures (3E)-3-[2-(3,5-Dichlorophenyl)hydrazin-1-ylidene]-1-(prop-2-en-1-yl)-2,3-dihydro-1H-indol-2-one under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
