Emamectin B1a is a semi-synthetic 4"-epimethylamino analogue of avermectin B1a prepared by oxidation of the 4"-hydroxy moiety and reductive amination. The introduction of the methylamino group greatly enhances the insecticidal potency of the avermectin class. Emamectin B1a, as a benzoate salt, is the major component (>90%) of the commercial insecticide/acaricide, emamectin.
Emamectin B1a is soluble in ethanol, methanol, DMF or DMSO. Poor water solubility.
