description Product Description
Isooctane is primarily used as a reference standard in determining the octane rating of fuels, particularly gasoline. Its high resistance to knocking makes it a key component in fuel testing, where it is assigned an octane rating of 100. This helps in evaluating and comparing the performance of other fuels in internal combustion engines. Additionally, it is used as a solvent in various industrial applications due to its stability and low reactivity. In laboratories, isooctane serves as a calibration standard for analytical instruments, ensuring accurate measurements in chemical analysis. Its properties also make it suitable for use in the formulation of high-performance fuels and as a blending agent to improve fuel efficiency and engine performance.
