Chemical Structure
Description
The occurrence of 1-(2,3-Dichlorophenyl)-1H-pyrrole-2,5-dione is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
1-(2,3-Dichlorophenyl)-1H-pyrrole-2,5-dione (CAS 37010-53-0) is a high-purity analytical reference standard with the molecular formula C10H5Cl2NO2 and a molecular weight of 242.06 g/mol.
1-(2,3-Dichlorophenyl)-1H-pyrrole-2,5-dione (C10H5Cl2NO2) 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. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
