Used as a key intermediate in the synthesis of organic semiconductors and conjugated polymers for optoelectronic devices. Its aldehyde and nitrile functional groups allow for versatile coupling reactions, making it valuable in creating fluorescent dyes and sensors. Also employed in the development of pharmaceuticals due to its ability to participate in multicomponent reactions for building complex heterocyclic structures. Commonly utilized in materials science for designing metal-organic frameworks (MOFs) and covalent organic frameworks (COFs) owing to its rigid, planar structure and reactive sites.
