Calcium pyrophosphate(CAS: 7790-76-3)

Calcium pyrophosphate (CAS: 7790-76-3) is a white, crystalline powder with a high melting point. Its molecular weight is approximately 140.09 g/mol. It is almost insoluble in water but soluble in acids. It is relatively stable under normal conditions but reacts with acids to form calcium phosphate and phosphoric acid.

Calcium pyrophosphate (CAS: 7790-76-3) is synthesized by reacting calcium carbonate or calcium oxide with phosphoric acid. The process typically involves heating a mixture of calcium oxide and phosphoric acid to form calcium pyrophosphate dihydrate. This method allows for high yields and good selectivity.

Calcium pyrophosphate (CAS: 7790-76-3) is used in the pharmaceutical industry as an ingredient in calcium supplements and as a pharmaceutical excipient. It is also used in the food industry as a food additive and in the plastics industry as a filler. Additionally, it is used in the ceramics and glass industries for its properties.

When handling Calcium pyrophosphate (CAS: 7790-76-3), it is important to use appropriate personal protective equipment (PPE), including gloves and safety goggles. Handling should be done in a well-ventilated area or a fume hood. In case of spills, they should be cleaned up immediately using appropriate methods. Always refer to the safety data sheet (SDS) for detailed handling instructions and emergency procedures.
