The molecular framework of 1,3-Isobenzofurandione, 4-[4-[1-[4-[(1,3-dihydro-1,3-dioxo-5-isobenzofuranyl)oxy]phenyl]-1-methylethyl]phenoxy]-, polymer with 1,3-benzenediamine and 4,4'-[(1-methylethylidene)bis(4,1-phenyleneoxy)]bis[1,3-isobenzofurandione] (C31H20O8C6H8N2) 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
