Description
N-Heptane (CAS 142-82-5, EC 205-563-8), also known as Heptane, Alkane C7, and NSC 62784, is a straight-chain saturated hydrocarbon solvent with the molecular formula C7H16. It carries no E-code designation and is classified under HS code 29011000.
In pharmaceutical manufacturing, n-heptane serves as an extraction and recrystallisation solvent, dissolving non-polar compounds while leaving polar impurities behind. In petrochemical and polymer processing, it acts as a carrier solvent and catalyst diluent, controlling reaction environments in Ziegler-Natta polymerisation. It is also used as a reference standard in octane rating tests for fuels.
N-Heptane is available in technical, reagent, and food-contact grades, with high-purity specifications conforming to FCC and Ph.Eur. standards where applicable. It is registered under REACH and subject to standard solvent handling regulations across EU member states. Packaging is typically supplied in drums and IBCs.
