2-Bromo-9H-carbazole（Cat No.:L035968）is a halogenated aromatic heterocycle derived from carbazole, featuring a bromine atom at the 2-position. This compound is widely used as a synthetic intermediate in the development of organic semiconductors, OLED materials, and pharmaceutical compounds. The presence of the bromine atom makes it highly suitable for palladium-catalyzed cross-coupling reactions, such as Suzuki, Stille, and Buchwald–Hartwig couplings, enabling the formation of complex, functionalized carbazole derivatives. Its rigid, planar structure contributes to excellent charge-transport properties, making it valuable in the design of optoelectronic and photoactive organic materials.
