Details

2,2,4-Trimethylpentane, 99%, ACS Grade (Isooctane)

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.

ACS grade chemicals are typically of higher purity compared to other grades and are suitable for use in analytical chemistry, research, and laboratory experiments where precision and accuracy are paramount.
