Used primarily as an intermediate in organic synthesis, this compound features an internal alkyne functionality with a reactive primary bromine site. The combination allows for sequential coupling reactions, such as Sonogashira (coupling the bromide with terminal alkynes) or Suzuki couplings, enabling the extension of carbon chains in pharmaceutical and agrochemical synthesis. It is also employed in the preparation of specialty monomers for advanced polymer systems where controlled molecular architecture is needed. Due to its reactivity, it is handled under inert conditions to prevent decomposition during storage and use.
