About 2,2,4-Trimethylpentane, 99%, Lab Grade

Isooctane, also known as 2,2,4-trimethylpentane, is a highly significant compound in the realm of fuel chemistry. It is one of the isomers of octane, a hydrocarbon with eight carbon atoms, and has the molecular formula C8H18. Isooctane is particularly renowned for its role as a reference standard in determining the octane rating of gasoline, a measure of a fuel's resistance to knocking in internal combustion engines. Due to its high resistance to knocking, iso-octane is assigned an octane rating of 100, making it the benchmark against which other fuels are compared. It is commonly used in fuel blending to improve gasoline quality by increasing its octane number, thereby enhancing engine performance and efficiency. Isooctane's stability and predictable combustion characteristics have solidified its position as a cornerstone in the development and optimization of automotive fuels worldwide.

Lab Grade typically refers to a specific quality of isooctane suited for laboratory use. While it may not adhere to the same stringent purity standards as higher grades like ACS (American Chemical Society) grade, it is still suitable for various laboratory applications
