Used primarily as an intermediate in organic synthesis, especially in pharmaceutical and agrochemical manufacturing. Its reactive bromomethyl group allows for easy alkylation and functionalization, making it valuable in constructing complex molecules. Commonly employed in the preparation of active pharmaceutical ingredients (APIs) where ester and bromide functionalities are leveraged for coupling reactions. Also utilized in the development of specialty polymers and as a building block in the synthesis of biologically active compounds. Its stability and reactivity profile make it suitable for controlled reactions under mild conditions.
