B-[3-(4-Dibenzothienyl)phenyl]boronic acid (CAS 1307859-67-1)

Application and positioning

A meta-phenylene linker that already carries a dibenzothiophene at the 3-position, so a single coupling completes a three-ring arm. It is used to build the meta-linked dibenzothiophene-phenylene fragments common in host and electron-transport materials. Laurand supplies it from audited Chinese producers in kilogram to multi-tonne lots, with the documentation your market requires.

Quality and documentation

• Anhydride content reported per lot, since arylboronic acids equilibrate with their anhydride form
• SDS in the language of your market, with GHS classification for the destination
• Pre-shipment sample for laboratory approval on first orders

Packaging and handling

• 1 kg, 5 kg and 25 kg fibre drums with inner PE liner; pack size confirmed at quotation
