Naphthalene is an aromatic hydrocarbon, found to be nonpolar in nature. It is generally produced from petroleum or coal-tar. Naphthalene, an organic compound, is widely used as an intermediate in chemical and plastic industry. Its other applications include, its role in the manufacturing of fungicides/insecticides and as a model compound for investigating the metabolism of polycyclic aromatic hydrocarbons (PAHs) by bacteria. The metabolism of this compound by Polaromonas naphthalenivorans CJ2 via the gentisate pathway followed by respirometry, GC-MS and cell-free enzyme assay has been studied.

Application

Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support. Naphthalene may be used as a certified reference material for the quantification of the analyte in honey samples using head-space solid-phase microextraction (HS-SPME) combined with gas chromatography–mass spectrometry (GC/MS) technique.

Packaging

Bottomless glass bottle. Contents are inside inserted fused cone.
