Description

Description générale

Toluene is a volatile organic compound and a priority environmental contaminant as designated by the US EPA.[1] The effect of toluene on the central nervous system myelin has been studied.[2]

Toluene is an aromatic hydrocarbon[3], which can be obtained from crude oil via cracking or distillation process.[4]

Application

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

Toluene may be used as an analytical reference standard for the quantification of the analyte in water samples[1] and engine oils[5] using gas chromatography (GC) with flame ionization detection (FID)[1] and mass spectrometry (MS).[5]
