Thieno[3,2-b]thiophene-2,5-diyldiboronic acid (CAS 1281324-46-6), molecular formula C6H6B2O4S2 and molecular weight 227.86 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Thieno[3,2-b]thiophene-2,5-diyldiboronic acid (C6H6B2O4S2) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, 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).
