Used as a versatile reagent in organic synthesis, particularly for introducing the 2-bromoethyl group. It serves as a protecting group modifier for alcohols and silanols due to its reactivity under mild conditions. Commonly employed in the preparation of functionalized polymers and silicon-based materials. Also utilized in the synthesis of pharmaceutical intermediates where selective alkylation is required. Its bromo functionality allows for further transformations via cross-coupling reactions or nucleophilic substitutions, making it valuable in building complex molecular architectures.
