General description

Di-n-octyl phthalate, belonging to the class of plasticizers, is found to be omnipresent in the environment. It is reported to be used in the manufacturing of flooring tiles, bottle cap liners, indirect food additives and toys.
Di-n-octyl phthalate (DNOP) is a mixed component of C6–C10 linear-chain phthalates which has the ability to impart flexibility in plastics and rubber materials. It is also used as plasticizer in PVC used in flooring and carpet tiles.

Application

DNOP has been used as standard during solid-phase microextraction followed by GC-MS analysis of phthalate esters in water sample examined after sonochemical degradation.
Di-n-octyl phthalate may be used as an analytical reference standard for the quantification of the analyte in:
  • Soil samples using micellar electro-kinetic chromatography (MEKC), further confirmed by gas chromatography with flame ionization detection (GC-FID).
  • Bottled water using gas chromatography coupled to mass spectrometry (GC-MS).
  • Plastic toys using gas chromatography with flame ionization detection (GC-FID).

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