Used primarily as a key intermediate in the synthesis of high-performance liquid crystalline polymers (LCPs). These polymers exhibit excellent thermal stability, mechanical strength, and chemical resistance, making them suitable for electronic components such as connectors, sockets, and printed circuit boards. Also employed in the production of advanced engineering plastics used in automotive and aerospace industries due to their ability to withstand high temperatures and harsh environments. Additionally, serves as a building block in organic synthesis for specialty esters and functional materials with tailored properties.
