Description
TCI B5897, 2-Bromo-7-iodo-9H-fluoren-9-one (CAS 867374-53-6), is a non-heterocyclic building block featuring dual halogen functional groups at the 2- and 7-positions of the fluorenone core, making it a valuable intermediate for palladium-catalyzed cross-coupling reactions such as Suzuki and Sonogashira couplings. This compound is widely employed in the synthesis of organic electronic materials including OLED emitters and organic semiconductors. It also serves as a key precursor in medicinal chemistry for constructing diverse molecular libraries through selective halogen substitution.
