Chemical Structure

5-Isobenzofurancarboxylic acid, 1,3-dihydro-1,3-dioxo-, polymer with 5,5'-carbonylbis[1,3-isobenzofurandione], 2,4-diisocyanato-1-methylbenzene and 1,1'-methylenebis[4-isocyanatobenzene] CAS 62009-59-0 chemical structure

Description

Based on its molecular formula C17H6O7C15H10N2O2C9H4O5C9H6N2O2, 5-Isobenzofurancarboxylic acid, 1,3-dihydro-1,3-dioxo-, polymer with 5,5'-carbonylbis[1,3-isobenzofurandione], 2,4-diisocyanato-1-methylbenzene and 1,1'-methylenebis[4-isocyanatobenzene] contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 938.77 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
