4,4,4',4',5,5,5',5'-octaethyl-2,2'-bi(1,3,2-dioxaborolane)

4,4,4',4',5,5,5',5'-Octaethyl-2,2'-bi(1,3,2-dioxaborolane) (CAS 2247367-07-1) is manufactured directly by BirdoTech to Chinese Pharmacopoeia (ChP) standard as a veterinary-grade product. The supplier's own description references a tetraborate coupling agent used as a Suzuki-Miyaura reaction catalyst precursor, though it cites a different CAS number than the one listed for this product, so that description should be treated with caution; the compound broadly belongs to the dioxaborolane/diboron family used in carbon-carbon bond-forming coupling chemistry.
