Used as a key intermediate in the synthesis of high-performance polymers, particularly in the production of liquid crystal polymers (LCPs) that exhibit excellent thermal stability, mechanical strength, and electrical insulation properties. It is also employed in the development of organic semiconductors and optoelectronic materials due to its rigid biphenyl structure that supports efficient charge transport. Additionally, it serves as a building block in pharmaceuticals and agrochemicals for constructing complex aromatic frameworks. Its acetyl functional groups allow for easy chemical modification, making it valuable in fine chemical synthesis and research.
