Application

t-Butyl bromide is primarily employed as an alkylating agent in organic synthesis, facilitating the introduction of the tert-butyl group into target molecules. It serves as a key intermediate in the preparation of pharmaceuticals, agrochemicals, and specialty chemicals via nucleophilic substitution reactions. Researchers also utilize it in the synthesis of Grignard reagents and as a building block for complex organic frameworks. Its reactivity makes it valuable in polymerization initiators and catalyst systems.
