(9-phenyl-9H-carbazol-2-yl)boronic acid (CAS 1001911-63-2)

Application and positioning

This is the 2-boronic acid isomer: the boron sits next to the nitrogen, so the coupled product is forced into a pronounced twist between the carbazole and the new ring. That twist is used deliberately in blue hosts, where breaking conjugation is what keeps the triplet level high. Laurand supplies it from audited Chinese producers in kilogram to multi-hundred-kilogram lots, with the documentation your market requires.

Quality and documentation

• Batch-specific Certificate of Analysis with HPLC or GC purity and a full impurity profile
• Trace metal report (Pd, Fe, Cu) on request — residual catalyst is what limits OLED device lifetime
• Water content by Karl Fischer and residual solvent data for solution-processed grades
• 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; amber glass bottles for gram to kilogram quantities on request
• Sealed and protected from light — carbazoles discolour under prolonged UV exposure
• Store at ambient temperature in a dry, dark warehouse, away from strong oxidising agents
