The substrate of CPPase is dimethylallyl diphosphate. The two products are diphosphate and chrysanthemyl diphosphate.

This enzyme is involved in the biosynthesis of pyrethrins, highly potent insecticides found in some flowers. The systematic name of this enzyme class is dimethylallyl-diphosphate:dimethylallyl-diphosphate dimethylallyltransferase (chrysanthemyl-diphosphate-forming).
