Used as an intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and agrochemicals. It serves as an alkylating agent due to the reactive bromine atom, enabling the introduction of a methoxybutyl group into various substrates. Commonly employed in the synthesis of active pharmaceutical ingredients (APIs) where ether linkages are required. Also utilized in the production of specialty chemicals such as surfactants and functionalized polymers. Its reactivity makes it valuable in forming carbon-oxygen and carbon-nitrogen bonds under controlled reaction conditions.
