N -Heptane

About N -Heptane

n-Heptane is a straight-chain (normal) aliphatic hydrocarbon belonging to the alkane family. It is a colorless, volatile liquid with a mild gasoline-like odor. It is derived primarily from petroleum refining and is commonly used as a non-polar solvent in industrial and laboratory settings.

It plays a crucial role in fuel testing, especially as the reference standard for octane rating (assigned a value of 0), meaning it represents poor resistance to engine knocking.
