General description

Di-n-octyl phthalate, belonging to the class of plasticizers, is found to be omnipresent in the environment.[94] It is reported to be used in the manufacturing of flooring tiles, bottle cap liners, indirect food additives and toys.[85]
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.[95][96]

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.[94]
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).
[94]
  • Bottled water using gas chromatography coupled to mass spectrometry (GC-MS).
  • [43]
  • Plastic toys using gas chromatography with flame ionization detection (GC-FID).
  • [96]
