General description

Dibenzyl phthalate, a diaryl phthalate, is extensively used as a plasticizer to modify the properties of the synthetic resin substrates, resulting in the improvement of flexibility and durability of the end products. It is considered as a potential environmental pollutant.

Application

Dibenzyl phthalate may be used as an analytical standard for the determination of the analyte in environmental samples, and benzyl butyl phthalate plasticizers used in lacquers by various chromatography techniques.
