Used as an intermediate in organic synthesis, particularly in pharmaceutical and agrochemical industries. It serves as a building block for introducing the tetrahydropyranyl group, which can act as a protecting group for alcohols and other functional groups during multi-step syntheses. Its bromine functionality allows for further transformations via cross-coupling reactions, such as Suzuki or Heck reactions, enabling the construction of complex molecules. Commonly employed in the development of bioactive compounds where controlled polarity and stability are required.
