4,8-Bis(2-ethylhexyl)benzo[1,2-b:4,5-b']dithiophene CAS 1234306-29-6 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

4,8-Bis(2-ethylhexyl)benzo[1,2-b:4,5-b']dithiophene (CAS 1234306-29-6) is a high-purity analytical reference standard with the molecular formula C26H38S2 and a molecular weight of 414.71 g/mol.

Owing to sulfur-containing functionality, a polycyclic aromatic system, 4,8-Bis(2-ethylhexyl)benzo[1,2-b:4,5-b']dithiophene is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 414.71 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
