dibenzo[b,d]furan-3-ylboronic acid (CAS 395087-89-5)

Application and positioning

The 3-isomer keeps the coupling point on the outer ring, away from the oxygen, so the resulting biaryl stays comparatively planar. It is used where the dibenzofuran-2-yl group would introduce too much twist for the intended photophysics. Laurand supplies it from audited Chinese producers in kilogram to multi-tonne lots, with the documentation your market requires.

Quality and documentation

• Batch-specific Certificate of Analysis with HPLC purity and water content by Karl Fischer
• 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
