Bis(2,3,3,3-tetrachloropropyl) ether is a type of ether compound that is used as a solvent, flame retardant, and plasticizer in various industrial applications.It is also used as a pesticide and fumigant, as well as a component in some transformer oils.

Bis(2,3,3,3-tetrachloropropyl) ether is an effective synergizing agent which is used in pesticide production.

S 421 is an effective synergizing agent which is used in pesticide production.

Octachlorodipropyl ether was manufactured through a high temperature electrophilic chlorination process applied to dipropyl ether or, more commonly, to a pre chlorinated phenyl ether precursor. Industrial producers typically began with a phenoxy phenyl framework and subjected it to exhaustive chlorination in the liquid phase using chlorine gas and a Lewis acid catalyst, driving substitution to the fully chlorinated 2,3,4,5 positions on both rings. The reaction mixture, containing various partially chlorinated congeners, was then distilled or crystallised to isolate the octachloro derivative. This route was favoured because it allowed stepwise control of chlorination and produced the high purity technical material required for its historical use as a synergist.
