3'-Ethoxy-Spinosyn L is the minor component in the second generation spinosyn family of bio-insecticides marketed as Spinetoram. 3'-Ethoxyspinosyn L is a semi-synthetic compound prepared by selective ethylation and hydrogenation of Spinosyn L, itself a fermentation product from a biosynthetically blocked mutant of Saccharopolyspora spinosa. As an insecticide, 3'-Ethoxy-spinosyn L is considered more potent and to have earlier onset and longer duration of action than combinations of Spinosyn A and D.
3'-Ethoxy-spinosyn L is soluble in ethanol, methanol, DMF and DMSO.
