(3'-chloro-[1,1'-biphenyl]-3-yl)boronic acid (CAS 1107603-42-8)

Application and positioning

A biphenyl boronic acid with a chlorine on the second ring, used when the target needs a meta-linked chlorinated phenyl arm rather than a flat biaryl. The C-Cl bond survives standard Suzuki conditions with Pd(PPh3)4, so the chlorine stays available for a later functionalisation step. 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
