Used primarily as a crosslinking agent in polymer chemistry, this compound enables the formation of highly crosslinked networks due to its three reactive bromomethyl groups. It is especially valuable in the synthesis of microporous organic polymers and covalent organic frameworks (COFs), where it acts as a trifunctional building block. Its rigid aromatic core and ability to undergo nucleophilic substitution or click chemistry make it suitable for constructing stable, porous materials used in gas storage, catalysis, and environmental remediation. Additionally, it serves as a precursor in the preparation of functional resins and dendritic macromolecules.
