9,9-Dimethyl-9H-Fluoren-2-yl-Boronic Acid (CAS 333432-28-3)

Application and positioning

The workhorse 2-boronic acid of the fluorene series: the partner you pair with aryl and heteroaryl bromides in Suzuki couplings. Assay is reported as boronic acid content, not only HPLC purity, because anhydride formation is what usually spoils a coupling. 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 — aromatic OLED intermediates discolour under prolonged UV exposure
• Store at ambient temperature in a dry, dark warehouse, away from strong oxidising agents
