Diisopropyl ether (also called isopropyl ether or 2-isopropoxyisopropane) is a transparent, colorless, mobile, extremely flammable liquid with a distinctive ethereal odor. It is soluble in organic solvents but poorly soluble in water, and it easily generates explosive peroxides. Isopropyl ether is used as a solvent for oils,waxes, resins, and dyes; and as a varnishremover.
