Description
General description
Heptane (n-Heptane) is a linear hydrocarbon. Its cetane number has been reported to be 56.[1]
Application
Greener 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).[2]
