dibenzo[b,d]furan-1-ylboronic acid (CAS 162607-19-4)

Application and positioning

The 1-position is the most crowded of the dibenzofuran sites, adjacent both to the oxygen and to the outer ring. It gives strongly twisted biaryls, which is useful when the target needs a wide dihedral angle rather than planar conjugation. 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
