Used primarily as a high-performance solvent in specialty applications, particularly in advanced polymer processing and electronic materials manufacturing. Its unique fused-ring structure provides exceptional thermal stability and low volatility, making it suitable for high-temperature reaction environments where conventional solvents degrade. It is also employed as a dielectric fluid in certain high-efficiency transformers and capacitors due to its excellent electrical insulation properties and chemical inertness. Additionally, it serves as a key intermediate in the synthesis of liquid crystalline compounds used in display technologies and optical sensors. Its low surface tension and high solvating power are leveraged in precision cleaning formulations for sensitive electronic components.
