Emamectin

CAS:119791-41-2

Molecular Formula:C49H75NO13

Alias

More Information

Emamectin B1a; Emamectin Benzoate; MK 243; Emmamectin Isomer; 4?-Deoxy-4?-epi-Methylaminoavermectin B1; (4?R)-4?-Deoxy-4?-(Methylamino)Avermectin B1; Avermectin B1, 4''-Deoxy-4''-(Methylamino)-, (4''R)-

Brief Introduction

Emamectin is the 4”-deoxy-4”-methylamino derivative of abamectin, a 16-membered macrycyclic lactone produced by the fermentation of the soil actinomycete Streptomyces avermitilis. It is generally prepared as the salt with benzoic acid, emamectin benzoate, which is a white or faintly yellow powder. Emamectin is widely used in the US and Canada as an insecticide because of its chloride channel activation properties.
