General descriptionHeptane (n-Heptane) is a linear hydrocarbon. Its cetane number has been reported to be 56.

ApplicationGreener alternatives to Hexane in HPLC.

Heptane (n-heptane) may be used to compose the solvent mixtures for the purification of N-acylpyrrolidine derivatives of fatty acid methyl esters (FAMEs) by TLC (Thin Layer Chromatography).
