Used as an intermediate in organic synthesis, particularly in the production of pharmaceuticals and agrochemicals. It plays a role in the preparation of compounds with potential biological activity. Its phosphonate group is valuable in creating analogs of natural phosphates, which are useful in drug development. The bromoheptyl chain allows for further functionalization, making it versatile in designing complex molecules. It is also employed in materials science for modifying surfaces or creating specialized polymers. Its reactivity makes it suitable for cross-coupling reactions, aiding in the construction of carbon-phosphorus bonds.
