Chemical Structure
Description
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.
(3E)-3-[(4-Chlorophenyl)imino]-1-[(2,6-dichlorophenyl)methyl]-5-methyl-2,3-dihydro-1H-indol-2-one (CAS 478043-07-1) is a high-purity analytical reference standard with the molecular formula C22H15Cl3N2O and a molecular weight of 429.73 g/mol.
Based on its molecular formula C22H15Cl3N2O, (3E)-3-[(4-Chlorophenyl)imino]-1-[(2,6-dichlorophenyl)methyl]-5-methyl-2,3-dihydro-1H-indol-2-one contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 429.73 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
