Used primarily as a reagent in organic synthesis, this compound serves as an alkylating agent for the introduction of the trimethylpropenyl group in pharmaceutical and agrochemical intermediates. Its vinylic bromide functionality enables cross-coupling reactions, such as Suzuki or Heck reactions, allowing the construction of complex molecular frameworks. It is also employed in the preparation of functionalized amines and nitrogen-containing heterocycles, which are key structural motifs in bioactive molecules. Due to its reactivity, it is handled under controlled conditions to avoid decomposition or unwanted side reactions.
