8-Quinolineboronic acid (CAS 86-58-8)

Application and positioning

The boronic acid sits at the 8-position, next to the ring nitrogen, which makes it the standard entry to 8-arylquinolines and to quinoline-based ligands. The neighbouring nitrogen accelerates protodeboration, so the coupling is normally run promptly in degassed solvent. 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
