9-([1,1'-biphenyl]-4-yl)-2-bromo-9H-carbazole (CAS 894791-46-9)

Application and positioning

2-Bromo-9-(4-biphenylyl)carbazole combines the N-biphenyl anchor with a bromide at the 2-position for late-stage coupling. It is the entry to 2-aryl-9-biphenylylcarbazoles, a series used to tune the triplet level of host materials. 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

• 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
