NPOE can be used as a plasticizer in a polymeric inclusion membrane (PIM) that enhances the transport of copper(II) in the solution of ammonia. It can be incorporated in a cellulose tri-acetate/carbon nanotube (CTA/CNT) based membrane, which is used in the transport and detection of melamine from milk samples.
2-Nitrophenyl octyl ether (NPOE) is an organic solvent, which is mainly used as a plasticizer and a charge transferring liquid that can be used in electrochemical devices. Its water solubility is low and has a high molar volume with a relative permittivity of 24.2.
