(3,5-dibromophenyl)boronic acid (CAS 117695-55-3)

Application and positioning

Two bromines sit symmetrically around the boronic acid, which makes this a hub building block for 1,3,5-trisubstituted benzenes. The bromines react in sequence under Suzuki or Buchwald-Hartwig conditions, so star-shaped hosts and dendrimer cores can be built outward from a single centre. 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
• Sealed, dry and protected from light — moisture uptake and oxidation are the main degradation routes
• Store at ambient temperature in a dry warehouse, away from oxidising agents
