5-Isobenzofurancarboxylic acid, 1,3-dihydro-1,3-dioxo-, polymer with 4,4'-oxybis[benzenamine] and 4,4'-[sulfonylbis(4,1-phenyleneoxy)]bis[benzenamine] CAS 72968-66-2

Description

The occurrence of 5-Isobenzofurancarboxylic acid, 1,3-dihydro-1,3-dioxo-, polymer with 4,4'-oxybis[benzenamine] and 4,4'-[sulfonylbis(4,1-phenyleneoxy)]bis[benzenamine] is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

5-Isobenzofurancarboxylic acid, 1,3-dihydro-1,3-dioxo-, polymer with 4,4'-oxybis[benzenamine] and 4,4'-[sulfonylbis(4,1-phenyleneoxy)]bis[benzenamine] (CAS 72968-66-2) is a high-purity analytical reference standard with the molecular formula C24H20N2O4SC12H12N2OC9H4O5 and a molecular weight of 824.86 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 5-Isobenzofurancarboxylic acid, 1,3-dihydro-1,3-dioxo-, polymer with 4,4'-oxybis[benzenamine] and 4,4'-[sulfonylbis(4,1-phenyleneoxy)]bis[benzenamine] is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 824.86 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
