Used as a key building block in organic synthesis, particularly in the preparation of conjugated polymers and molecular frameworks for optoelectronic materials. Its multiple alkyne groups enable click chemistry reactions, making it valuable in constructing complex molecular architectures such as covalent organic frameworks (COFs). Also employed in cross-coupling reactions to develop pharmaceutical intermediates and functionalized aromatic systems. The bromine moiety allows for further metal-catalyzed functionalization, enhancing its utility in materials science and drug discovery research.
