2-Amino-9,9-dimethylfluorene (CAS 108714-73-4)

Application and positioning

The amine is the donor end: Buchwald coupling onto aryl bromides gives triarylamines without going through a nitro reduction. The two methyls on C-9 keep the molecules from stacking, which is why it is preferred over plain 2-aminofluorene in hole-transport layers. 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
