Calcium hypophosphite|CAS 7789-79-9

Calcium hypophosphite，CAS 7789-79-9 is an inorganic salt. Its appearance is typically a white or greyish-white crystalline powder. It is soluble in water but insoluble in alcohol. As a hypophosphite, it is a strong reducing agent. It is stable under normal conditions,as for strong reducing agent,it’ s can be used in many ways,such as electroless plating industry,chemical intermediate,etc.

Primary Uses

The main applications of calcium hypophosphite are based on its properties as a source of hypophosphite ions.

1. Electroless Nickel Plating Agent: This is its major industrial use. It serves as a fundamental reducing agent in electroless nickel plating baths.In this process, it reduces nickel ions to metallic nickel without an electric current, allowing for uniform coatings on complex shapes and non-conductive materials like plastics.

2. Chemical Intermediate: It is used as a starting material or intermediate in the synthesis of other hypophosphite salts and various organic phosphorus compounds.

3. Traditional and Niche Applications: It was historically used in medicine as a dietary supplement and tonic, but this use is now outdated and not recommended due to potential toxicity. It has also been used as a stabilizer in some plastics.

Safety and Handling

Handling calcium hypophosphite requires caution due to the hazards associated with its decomposition products.
