Chemical Structure
Description
The occurrence of 4,8-Bis(5-(2-ethylhexyl)thieno[3,2-b]thiophen-2-yl)benzo[1,2-b:4,5-b']dithiophene is closely related to sulfur-containing functionality, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4,8-Bis(5-(2-ethylhexyl)thieno[3,2-b]thiophen-2-yl)benzo[1,2-b:4,5-b']dithiophene (CAS 1494614-30-0), molecular formula C38H42S6 and molecular weight 691.13 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to sulfur-containing functionality, a polycyclic aromatic system, 4,8-Bis(5-(2-ethylhexyl)thieno[3,2-b]thiophen-2-yl)benzo[1,2-b:4,5-b']dithiophene is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 691.13 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
