Used primarily in organic synthesis as an intermediate for the preparation of various pharmaceuticals and fine chemicals. It plays a key role in the development of compounds with potential biological activity, particularly in the synthesis of benzaldehyde derivatives. Its benzyloxy group offers protection for hydroxyl functionalities during complex reactions, while the bromine atom allows for further functionalization through cross-coupling reactions. This compound is also utilized in the research and development of new materials, including polymers and dyes, where its reactive aldehyde group can be exploited for further chemical modifications.
