Description

Structurally, 5',5'"-Bis(3,5-dicarboxyphenyl)-5"-(3,3",5,5"-tetracarboxy-[1,1':3',1"-terphenyl]-5'-yl)-[1,1':3',1":3",1'":3'",1""-quinquephenyl]-3,3"",5,5""-tetracarboxylic acid (C72H42O24) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 52.0, corresponding to approximately 52 ring(s) or double-bond equivalent(s). With a molecular weight of 1291.09 g/mol, it falls into the high-molecular-weight range. 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).

CATO supplies 5',5'"-Bis(3,5-dicarboxyphenyl)-5"-(3,3",5,5"-tetracarboxy-[1,1':3',1"-terphenyl]-5'-yl)-[1,1':3',1":3",1'":3'",1""-quinquephenyl]-3,3"",5,5""-tetracarboxylic acid (CAS 1621703-84-1), a certified reference material (molecular formula C72H42O24, MW 1291.09 g/mol) for analytical method development and quality control.

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.
