[9-(2-Naphthalenyl)-9H-carbazol-3-yl]-boronic acid (CAS 1133057-98-3)

Application and positioning

A carbazole already N-substituted with 2-naphthyl and borylated at the 3-position, so the hole-transporting core is built in one coupling. It is used for solution-processable OLED hosts and for amorphous hole-transport materials with a high triplet energy. 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
