Used as a key intermediate in the synthesis of fluorescent dyes and organic semiconductors due to its ability to form stable derivatives with extended π-conjugation. It is also employed in the preparation of coordination polymers and metal-organic frameworks (MOFs), where its carboxylic acid groups act as linkers for metal ions. Additionally, it serves in the development of photoactive materials and has been explored in the design of sensors for metal cations. Its bromine substituents allow for further functionalization via cross-coupling reactions, making it valuable in fine chemical and pharmaceutical synthesis.
