Applications Methyl thiocyanate is a reagent that is used in the synthesis of WAK 4103 (W498200), which is a metabolite of Imidacloprid (I274990), a neonicotinoid; the active ingredient in certain neuro-active insecticides. Reports show that when exposed to neonicotinid pesticides honeybees have probelms returnign home after foraging and bumblebee colonies grow poorly and produce fewer queens.Nauen, R., et. al.: Pestic.
