Chemical Structure
Description
The occurrence of 2',2",2"',5',5",5"'-Hexamethyl-[1,1':4',1":4",1'":4'",1""-quinquephenyl]-4,4""-dicarboxylic acid 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.
2',2",2"',5',5",5"'-Hexamethyl-[1,1':4',1":4",1'":4'",1""-quinquephenyl]-4,4""-dicarboxylic acid (CAS 2249751-97-9) is a high-purity analytical reference standard with the molecular formula C38H34O4 and a molecular weight of 554.67 g/mol.
Structurally, 2',2",2"',5',5",5"'-Hexamethyl-[1,1':4',1":4",1'":4'",1""-quinquephenyl]-4,4""-dicarboxylic acid (C38H34O4) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 22.0, corresponding to approximately 22 ring(s) or double-bond equivalent(s). With a molecular weight of 554.67 g/mol, it falls into the moderately-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).
