Copper acetoarsenite (Paris Green or Emerald Green) is an inorganic copper-arsenic compound formerly used as a pigment, wood preservative and agricultural insecticide. Today it is primarily supplied as a laboratory reagent, analytical reference material, museum conservation reference, and research chemical because of its extreme toxicity. Commercial use is heavily restricted or prohibited in many countries.
