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 ester groups into target molecules. Commonly employed in the synthesis of active pharmaceutical ingredients (APIs) where controlled carbon chain extension is required. Also utilized in the production of specialty polymers and as a building block in the formation of chiral compounds through nucleophilic substitution or esterification reactions. Its volatility and reactivity make it suitable for use in controlled reaction environments.
