Tetrasodium pyrophosphate CAS 7722-88-5
Sodium pyrophosphate, also called Tetrasodium pyrophosphate or TSPP is used in the laboratory as a buffering agent. The compound has been shown to be useful in the preparation of an EDTA-sodium pyrophosphate extraction buffer for microcystin analysis of soil samples. Tetrasodium pyrophosphate is an odorless, white powder or granules. It is used in water softener, buffering agent, thickening agent, dispersing agent, wool de-fatting agent, metal cleaner, soap and synthetic detergent builder, general sequestering agent, in electrodeposition of metals. It also acts as a tartar control agent in toothpaste and dental floss. In addition, it is used as a chelating agent in antimicrobial studies. It is also used as a food additive in common foods such as chicken nuggets, crab meat and canned tuna.

Tetrasodium Pyrophosphate is a coagulant, emulsifier, and sequestrant that is mildly alkaline, with a ph of 10. Tetrasodium Pyrophosphate is moderately soluble in water, with a solubility of 0.8 g/100 ml at 25°c. Tetrasodium Pyrophosphate is used as a coagulant in noncooked instant puddings to provide thicken- ing. Tetrasodium Pyrophosphate functions in cheese to reduce the meltability and fat separa- tion. it is used as a dispersant in malted milk and chocolate drink powders. Tetrasodium Pyrophosphate prevents crystal formation in tuna. Tetrasodium Pyrophosphate is also termed sodium pyrophosphate, tetrasodium diphosphate, and tspp.
