Product Details

Cupric hydroxide CAS#20427-59-2

Cupric hydroxide appears as a blue powder and it is not stable. Cupric hydroxide is used as a mordant and pigment, in the manufacture of many copper salts, and for staining paper. It is used as a fungicide/bactericide on fruits, vegetables, and ornamentals. It can be used as catalyst, feed additive, and a cuprammonium rayon process reagent to make the first semi-synthetic fiber product, Rayon.

Product Application Of Cupric hydroxide CAS#20427-59-2

Used as a raw material in chemical processing and catalyst manufacturing. Copper(II) hydroxide is used as ceramic colorant. In organic synthesis, it is used as a catalyst to prepare 1-((2-aminoethyl)amino)anthraquinone, 1-amino-4-((2-aminoethyl)amino)anthraquinone by reacting with 1-bromoanthraquinone or 1-amino-4-bromoanthraquinone respectively. It is involved in the synthesis of benzoic acid and octanoic acid. It is used as a precursor in the production of rayon, battery electrodes and other copper salts It is also used as a dye mordant, paper colorant, pigment and feed additive.
