Copper acetate

Copper(II) acetate, also referred to as cupric acetate, is the chemical compound with the formula Cu(OAc)2 where AcO− is acetate (CH 3CO− 2). The hydrated derivative contains one molecule of water for each Cu atom. Anhydrous Cu(OAc)2 is a dark green crystalline solid, whereas Cu2(OAc)4(H2O)2 is more bluish-green. Copper acetates are used as reagents for the synthesis of various inorganic and organic compounds. Copper acetate, like all copper compounds, emits a blue-green glow in a flame. Naturally occurring form of copper(II) acetate is mineral hoganite. Copper acetate is used as a catalyst, oxidizer, and as a blue-green pigment for making paint and other art supplies. It is used as an insecticide, in the preparation of other chemicals, as a fungicide, and mildew preventive.
