General description

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.
This certified reference material (CRM) is produced and certified in accordance with ISO/IEC 17025 and ISO 17034. This CRM is traceable to primary material from an NMI, e.g. NIST or NMIJ.
Certified content by quantitative NMR incl. uncertainty and expiry date are given on the certificate.

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.
