CuC8H4N22

CuC8H4N22, also known as copper(II) chloride dihydrate, is a chemical compound with the formula CuCl2·2H2O. It is a blue-green crystalline solid that is commonly used in various chemical and industrial applications. The compound consists of copper(II) ions (Cu2+) coordinated with two chloride ions (Cl-) and two water molecules (H2O). It is highly soluble in water and forms a blue-green solution.

Copper(II) chloride dihydrate is often used as a precursor in the synthesis of other copper compounds. It is also employed in the production of catalysts, pigments, and fungicides. In analytical chemistry, it is used as a reagent for the detection and quantification of various substances, such as ammonia and amines.

The compound is prepared by reacting copper(II) oxide or copper(II) carbonate with hydrochloric acid, followed by crystallization from water. It can be stored at room temperature but should be kept away from heat sources and incompatible substances, such as strong oxidizing agents and strong bases.

CuC8H4N22 is a hazardous substance and should be handled with care. It can cause skin and eye irritation, and inhalation of its dust can lead to respiratory issues. Proper personal protective equipment, such as gloves, safety glasses, and a lab coat, should be worn when handling the compound. In case of accidental exposure, seek medical attention immediately and follow the appropriate spill response procedures.
