4',5'-Bis(3,5-dicarboxyphenyl)-[1,1':2',1"-terphenyl]-3,3'',5,5"-tetracarboxylic acid CAS 1364673-98-2

Description

4',5'-Bis(3,5-dicarboxyphenyl)-[1,1':2',1"-terphenyl]-3,3'',5,5"-tetracarboxylic acid (CAS 1364673-98-2) is a high-purity analytical reference standard with the molecular formula C38H22O16 and a molecular weight of 734.57 g/mol.

Based on its molecular formula C38H22O16, 4',5'-Bis(3,5-dicarboxyphenyl)-[1,1':2',1"-terphenyl]-3,3'',5,5"-tetracarboxylic acid contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 734.57 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
