Used as a key intermediate in organic synthesis, particularly in the preparation of long-chain alkyl bromides and functionalized fatty acid derivatives. Its bromine terminus allows for further coupling reactions, such as nucleophilic substitutions or metal-catalyzed cross-couplings, enabling the construction of complex molecules in pharmaceutical and polymer research. The tert-butyl ester group offers stability during reactions and can be selectively deprotected under mild acidic conditions, making it valuable in multi-step synthesis where controlled reactivity is required. It is also employed in the development of surface modifiers and specialty chemicals requiring precise chain length and functional group placement.
