Pyrethrin II – CAS 121-29-9

Abstract

Pyrethrins (CAS 121-29-9) are a class of organic compounds derived from Chrysanthemum cinerariifolium (Dalmatian chrysanthemum). They are a naturally occurring, potent insecticide found in the flowers of the plant. There are 6 compounds that occur naturally in pyrethrin mixtures: Pyrethrin I, Cinerin I, Jasmolin I, Pyrethrin II, Cinerin II, and Jasmolin II.

Our Pyrethrin reference standards are purified using CPC, ensuring the highest purity available anywhere.

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.
