FAQ

What is Cupric Hydroxide (CAS: 20427-59-2)?

Cupric hydroxide is a chemical compound with the formula Cu(OH)₂. It is a blue-green solid that is insoluble in water. This compound is commonly used as a pigment and in various industrial applications. It has a high pH and is a basic compound, often appearing as a precipitate in aqueous solutions.

What are the main uses of Cupric Hydroxide (CAS: 20427-59-2)?

Cupric hydroxide is widely used in the production of ceramics, glass, and pigments. It also serves as a precursor for other copper compounds in chemical synthesis. In the pharmaceutical industry, it can be used as an antiseptic or in some drug formulations. Additionally, it finds applications in electroplating and as a catalyst in certain reactions.

Is Cupric Hydroxide (CAS: 20427-59-2) safe?

Cupric hydroxide is generally considered safe when handled properly, but it may cause skin and eye irritation. Inhalation of its dust can be harmful, so protective equipment such as gloves, goggles, and a dust mask should be used. It is classified as a substance with low acute toxicity but should be kept away from children and not ingested. Safety standards recommend following OSHA and EPA guidelines for its use and disposal.

How should Cupric Hydroxide (CAS: 20427-59-2) be stored?

Cupric hydroxide should be stored in a cool, dry, and well-ventilated area, away from moisture and light. It is best kept in a sealed, airtight container made of glass or plastic to prevent contamination. Due to its hygroscopic nature, exposure to humidity can affect its stability. Always store it in a location that is inaccessible to children and follow proper chemical storage protocols.
