Pyrethrolone – CAS 487-67-2

Abstract

Pyrethrum oil (CAS 487-67-2) (Chrysanthemum cinerariifolium) contains six pyrethrins, which belong to two groups: (1) pyrethrins I group and (2) pyrethrins II group. These six pyrethrins are structurally related esters, either of trans-chrysanthemic acid (pyrethrins I group) or pyrethric acid (pyrethrins II group). Pyrethrin I, jasmolin I, and cinerin I constitute group I and are all esters of trans-chrysanthemic acid. Pyrethrin II, jasmolin II, and cinerin II constitute group II and are all esters of pyrethric acid. Each ester is insecticidally active. Pyrethrolone (CAS 487-67-2)is the alcohol moiety of pyrethrin I and pyrethrin II; furthermore, hydrolysis of pyrethrin II produces pyrethric acid and pyrethrolone.
