Dipropyl phthalate is used as a plasticizer in certain polymer formulations coatings and specialty chemical applications. It may also be used in laboratory research and chemical formulations.

It is used to improve flexibility processability and workability in compatible materials. Its specific function depends on the formulation and intended industrial application.

Dipropyl phthalate is an organic phthalate ester generally described as a colorless to pale-yellow oily liquid. It is relatively low in volatility and has limited solubility in water.
