Pyrethrin I – CAS 121-21-1

Abstract

Pyrethrin I (CAS 121-21-1)is one of the six pyrethrin esters derived from Chrysanthemum cinerariifolium (Dalmatian chrysanthemum). Pyrethrins are a naturally occurring, potent insecticide found in the flowers of the plant. The naturally occurring pyrethrins include Pyrethrin I, Cinerin I, Jasmolin I, Pyrethrin II, Cinerin II, and Jasmolin II. Pyrethrins are considered organic pesticides when they do not contain synthetic adjuvants.

The market has shown favor for pyrethrins over organophosphates and organochlorides as the latter have displayed persistent toxic effects to humans. Pyrethrins are among the safest pesticides as they experience rapid degradation in the environment.

Our collection of pyrethrin ester reference standards has been used to qualify commercial pyrethrin products globally. Please find our entire collection here. Please note, MOQ for all pyrethrin standards is 10 mg.
