Description
The occurrence of 5''-(4'-Carboxy-[1,1'-biphenyl]-2-yl)-[1,1':2',1'':3'',1''':2''',1''''-quinquephenyl]-4,4''''-dicarboxylicacid is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
5''-(4'-Carboxy-[1,1'-biphenyl]-2-yl)-[1,1':2',1'':3'',1''':2''',1''''-quinquephenyl]-4,4''''-dicarboxylicacid (CAS 1351983-66-8), molecular formula C45H30O6 and molecular weight 666.72 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 5''-(4'-Carboxy-[1,1'-biphenyl]-2-yl)-[1,1':2',1'':3'',1''':2''',1''''-quinquephenyl]-4,4''''-dicarboxylicacid (C45H30O6) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
