Chemical Structure
Description
N,N'-Bis(3,5-dichlorophenyl)-2-[(1E)-(methoxyimino)methyl]propanediamide (C17H13Cl4N3O3) 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
N,N'-Bis(3,5-dichlorophenyl)-2-[(1E)-(methoxyimino)methyl]propanediamide (CAS 339096-48-9) is a high-purity analytical reference standard with the molecular formula C17H13Cl4N3O3 and a molecular weight of 449.12 g/mol.
