Chemical Structure
Description
The molecular framework of 1,3-Isobenzofurandione, 5,5'-carbonylbis-, polymer with 1,3-diisocyanatomethylbenzene and 1,1'-methylenebis[isocyanatobenzene] (C17H6O7C15H14N2O2C9H6N2O2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).
1,3-Isobenzofurandione, 5,5'-carbonylbis-, polymer with 1,3-diisocyanatomethylbenzene and 1,1'-methylenebis[isocyanatobenzene] (CAS 152187-64-9) is a high-purity analytical reference standard with the molecular formula C17H6O7C15H14N2O2C9H6N2O2 and a molecular weight of 750.68 g/mol.
