    General description

    We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. Heptane is an environmentally preferable solvent and greener alternative to hexane for chromatographic purification and thus has been enhanced for "Safer Solvents and Auxiliaries". Click here for more information.
    Tools and techniques for solvent selection: green solvent selection guides.

    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]
