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] Features and Benefits Greener alternative for hexane Other Notes What is a green solvent? A comprehensive framework for the environmental assessment of solvents Tools and techniques for solvent selection: green solvent selection guides Important notice The article number 34873-4X2.5L will be discontinued.
