Chemical Structure

1,3-Isobenzofurandione, 5,5'-[(1-methylethylidene)bis(4,1-phenyleneoxy)]bis-, polymer with 1,3-benzenediamine and 1,3-isobenzofurandione CAS 61594-31-8 chemical structure

Description

Structurally, 1,3-Isobenzofurandione, 5,5'-[(1-methylethylidene)bis(4,1-phenyleneoxy)]bis-, polymer with 1,3-benzenediamine and 1,3-isobenzofurandione (C31H20O8C8H4O3C6H8N2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 31.0, corresponding to approximately 31 ring(s) or double-bond equivalent(s). With a molecular weight of 776.75 g/mol, it falls into the high-molecular-weight range. 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).
