General description

Isoprene is a reactive aliphatic hydrocarbon that originates as a byproduct of cholesterol synthesis.
This substance is listed on the positive list of the EU regulation 10/2011 for plastics intended to come into contact with food. Find all available reference materials for compounds listed in 10/2011 here

Application

Isoprene may be used as an analytical reference standard for the quantification of the analyte in human breath samples using substrate-integrated hollow waveguide mid-infrared sensors and thermal desorption gas chromatography with ultraviolet detection.
Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.
