Description

General description

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.
