3-Chlorophenylboronic Acid (CAS 63503-60-6)

Application and positioning

The meta-chloro isomer is the standard partner for installing a 3-chlorophenyl group in Suzuki-Miyaura couplings. Under Pd(PPh3)4 and a mild base the aryl chloride is largely untouched, so the product can be carried into a second coupling. 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
