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 primary reference fuel (PRF) for the rating of octane numbers of fuels in internal combustion engines. Its cetane number has been reported to be 56. Mechanism and kinetic studies of its oxidation in flow reactors, shock tubes and rapid compression machines have been proposed. Its thermal decomposition has been studied under different conditions of temperature and pressure. Its oxidative dehydrogenation in the presence of magnesium oxide supported vanadium catalyst has been investigated. Molybdenum phosphide supported on Hβ zeolite (MoP/Hβ) catalyzed hydroisomerization of n-heptane has been reported to be enhanced by doping with secondary metals (Cr, Ni or Ce).

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).
  • To generate chiral alcohols and heptanones, via whole cell double oxidation.
  • As a solvent in the synthesis of isopropyl acetate, via esterification of acetic acid with isopropyl alcohol catalyzed by lipase immobilized on silica.

Lot and Batch Numbers can be found on a product's label following the words 'Lot' or 'Batch'.

Aldrich Products

  • For a lot number such as TO09019TO, enter it as 09019TO (without the first two letters 'TO').

  • For a lot number with a filling-code such as 05427ES-021, enter it as 05427ES (without the filling-code '-021').

  • For a lot number with a filling-code such as STBB0728K9, enter it as STBB0728 without the filling-code 'K9'.

Not Finding What You Are Looking For?

In some cases, a COA may not be available online. If your search was unable to find the COA you can request one.
