4-Bromophenylboronic acid is primarily used in Suzuki–Miyaura cross-coupling reactions with aryl or vinyl halides under palladium catalysis. This reaction forms C–C bonds with excellent functional group tolerance and mild conditions. It can also be used in Chan–Lam coupling for C–N and C–O bond formation without transition metal catalysts under aerobic conditions.

As a brominated compound, 4-Bromophenylboronic acid is an excellent substrate for palladium-catalyzed cross-coupling reactions including Suzuki, Heck, Negishi, Sonogashira, and Buchwald–Hartwig amination. It can also be used for Grignard reagent preparation, metal–halogen exchange with organolithium reagents, and nucleophilic substitution reactions.
