Used as a key intermediate in the synthesis of functionalized polymers and specialty resins. Its reactive bromomethyl group allows for easy alkylation or quaternization, making it valuable in modifying polymer backbones for improved solubility or reactivity. Commonly employed in the development of crosslinking agents for coatings and adhesives, where it contributes to enhanced thermal and chemical resistance. Also utilized in the preparation of metal-organic frameworks (MOFs) due to its ability to act as a rigid, bifunctional linker. In pharmaceutical research, it serves as a building block for constructing complex ester-based prodrugs or bioactive molecules requiring controlled release properties. Its ester groups can be hydrolyzed selectively, enabling stepwise functionalization in multi-step organic syntheses.
