Whereas at 20 °C, diethyl ether will dissolve 1% by weight water, diisopropyl ether dissolves 0.88%. Diisopropyl ether is used as a specialized solvent to remove or extract polar organic compounds from aqueous solutions, e. g. phenols, ethanol, acetic acid. It has also been used as an antiknock agent. In the laboratory, diisopropyl ether is useful for recrystallizations because it has a wide liquid range. Diisopropyl ether is used for converting bromoboranes, which are thermally labile, into isopropoxy derivatives.

Diisopropyl ether forms explosive peroxides upon standing in air. This reaction proceeds more easily than for ethyl ether due to the increased lability of the C H bond adjacent to oxygen. Many explosions have been known to occur during handling or processing of old diisopropyl ether. Some laboratory procedures recommend use of freshly opened bottles. Peroxides may be removed by shaking the ether with an aqueous solution of iron(II) sulfate or sodium metabisulfite. For safety reasons, methyl tert butyl ether is often used as an alternative solvent.
