Used in the synthesis of metal-organic frameworks (MOFs) due to its ability to act as a linker with both carboxylic acid groups and a reactive iodo site. The iodo group allows for further functionalization through cross-coupling reactions, enabling tailored porosity and functionality in porous materials. Applied in gas storage, separation processes, and catalysis. Also serves as an intermediate in pharmaceutical and agrochemical synthesis where halogenated aromatic structures are required. Its bifunctional nature supports use in polymer chemistry for constructing specialty polyamides and polyesters with enhanced thermal and mechanical properties.
