4,4',4'',4'''-(Cycloocta[1,2-b:4,3-b':5,6-b'':8,7-b''']tetrathiophene-2,5,8,11-tetrayl)tetrabenzaldehyde (CAS 2625875-84-3) is a high-purity analytical reference standard with the molecular formula C44H24O4S4 and a molecular weight of 744.92 g/mol.
The molecular framework of 4,4',4'',4'''-(Cycloocta[1,2-b:4,3-b':5,6-b'':8,7-b''']tetrathiophene-2,5,8,11-tetrayl)tetrabenzaldehyde (C44H24O4S4) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
