Used as a key intermediate in organic synthesis, particularly in the preparation of functionalized naphthalene derivatives for optoelectronic materials. It serves in the construction of conjugated polymers and organic semiconductors due to its ability to undergo cross-coupling reactions. Also employed in the synthesis of fluorescent dyes and probes, where the dual bromine functionality allows for selective substitution and extension of π-conjugated systems. Its reactivity makes it valuable in pharmaceutical research for building complex polycyclic structures.
