Used as an intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and agrochemicals. Its structure allows for cross-coupling reactions, such as Suzuki or Negishi couplings, enabling the formation of carbon-carbon bonds in complex molecules. The bromine atom serves as a good leaving group, facilitating substitution reactions. The 1-methylcyclopropyl group can influence the steric and electronic properties of the final product, making it useful in the development of bioactive compounds. Also employed in research settings to build aromatic frameworks with constrained aliphatic rings for structure-activity relationship studies.
