Chemical Structure
Description
The occurrence of [(3Z)-1-[(2,6-Dichlorophenyl)methyl]-2-oxo-2,3-dihydro-1H-indol-3-ylidene]amino 3-methylbutanoate is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
[(3Z)-1-[(2,6-Dichlorophenyl)methyl]-2-oxo-2,3-dihydro-1H-indol-3-ylidene]amino 3-methylbutanoate (CAS 252579-07-0) is a high-purity analytical reference standard with the molecular formula C20H18Cl2N2O3 and a molecular weight of 405.27 g/mol.
[(3Z)-1-[(2,6-Dichlorophenyl)methyl]-2-oxo-2,3-dihydro-1H-indol-3-ylidene]amino 3-methylbutanoate (C20H18Cl2N2O3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
