Used as a key intermediate in the synthesis of functionalized fluorene derivatives, which are important in the development of organic semiconductors and optoelectronic materials. Its bromo and hydroxyl groups allow for selective cross-coupling reactions and further derivatization, making it valuable in the preparation of conjugated polymers and small-molecule emitters for OLEDs. Also serves as a building block in pharmaceutical research, particularly in the design of bioactive molecules with sterically hindered architectures. The presence of the tertiary alcohol and aromatic bromide enables use in palladium-catalyzed coupling reactions, facilitating the construction of complex polycyclic systems.
