Chemical Structure
Description
(4,8-Diethoxybenzo[1,2-b:4,5-b']dithiophene-2,6-diyl)diboronic acid (C14H16B2O6S2) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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).
(4,8-Diethoxybenzo[1,2-b:4,5-b']dithiophene-2,6-diyl)diboronic acid (CAS 2023811-72-3) is a high-purity analytical reference standard with the molecular formula C14H16B2O6S2 and a molecular weight of 366.03 g/mol.
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.
