4'',6'-Diamino-5',5''-bis(3,5-dicarboxyphenyl)-[1,1':3',1'':3'',1'''-quaterphenyl]-3,3''',5,5'''-tetracarboxylic acid CAS 2055593-90-1

Description

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 4'',6'-Diamino-5',5''-bis(3,5-dicarboxyphenyl)-[1,1':3',1'':3'',1'''-quaterphenyl]-3,3''',5,5'''-tetracarboxylic acid is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 840.70 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).

4'',6'-Diamino-5',5''-bis(3,5-dicarboxyphenyl)-[1,1':3',1'':3'',1'''-quaterphenyl]-3,3''',5,5'''-tetracarboxylic acid (CAS 2055593-90-1), molecular formula C44H28N2O16 and molecular weight 840.70 g/mol, is a CATO reference standard with documented purity and traceability.
