What is (E)-BETA-FARNESENE?
Description
trans-β-Farnesene, also known as (E)-β-farnesene, is a member of a group of sesquiterpene isomers, three of which occur in natural oils. The natural trans-β compound is used by aphids as a death signal to warn away other individuals and by potatoes to repel insects. A California company is?using synthetic mixed farnesenes as a starting material?for products ranging from biodiesel to perfumes.
