Sodium pyrophosphate decahydrate, also called tetrabasic 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. Sodium pyrophosphate dibasic also called, disodium pyrophosphate or DSPP (sc-251047) has been used as a chelating agent in antimicrobial studies.
