Chemical Structure
Description
2-[(2,5-Dichlorophenyl)methoxy]-2,3-dihydro-1H-isoindole-1,3-dione (C15H9Cl2NO3) contains a nitrogen-containing heterocyclic scaffold, 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, 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.
2-[(2,5-Dichlorophenyl)methoxy]-2,3-dihydro-1H-isoindole-1,3-dione (CAS 321430-35-7), molecular formula C15H9Cl2NO3 and molecular weight 322.14 g/mol, is a CATO reference standard with documented purity and traceability.
