How Stereochemistry Considerations Can Improve Pesticide Safety

摘要：

About 30％ of pesticides are chiral molecules and therefore exist as two or more stereoisomers, which can differ significantly in their toxicity, biodegradation, and persistence. Such differences can impact their relative safety to humans and environmental species. Enantiomers, mirror image optical isomers, are the best known examples of stereoisomers that can show these differences. However, the great majority of chiral pesticides are manufactured and applied as their racemates; i. e. , equal mixtures of each enantiomer.
