Description

General description

Undecane is obtained from the refining of petroleum. It is a component of gasoline and is generally used in organic synthesis, petroleum research and as a distillation chaser.[1]

Application

Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.

Undecane has been used as a standard in quantitatively determining the presence of iso-furans and F2-isoprostanes in biological fluids and tissues, using gas chromatography coupled with mass spectrometry (GC/MS).
