Used as a lubricant in high-performance instruments due to its excellent thermal stability and low volatility. Commonly employed in vacuum systems and precision machinery where long-term reliability is required. Also serves as an adjuvant in immunological research to induce chronic inflammation or plasmacytoma in animal models. Frequently utilized in chromatography as a retention index standard for hydrocarbon analysis. Its inert nature makes it suitable for use in cosmetic formulations as an emollient and skin-conditioning agent.
