General description

2-Methylnaphthalene belongs to the class of polycyclic aromatic hydrocarbons (PAHs), found to be a major environmental contaminant. It can occur in high concentrations in a variety of commercial products including coal tar, crude oil, etc.

Application

2-Methylnaphthalene may be used to identify the analyte from thermal degradation of bituminous/anthracite coals, tyres, and cellulose samples using gas chromatography-mass spectrometry (GC-MS) technique.
Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.

The sulfate-reducing culture N47 can utilize naphthalene or 2-methylnaphthalene as the sole carbon source and electron donor. Here we show that the initial reaction in the naphthalene degradation pathway is a methylation to 2-methylnaphthalene which then undergoes the subsequent oxidation
