Sodium pyrophosphate, 200mM buffer soln. is used in the laboratory as a buffering agent. DSPP has been used as a chelating agent in antimicrobial studies. Tetrabasic pyrophosphate or TSPP (sc-203404; sc-236921) has shown to be useful in the preparation of an EDTA-sodium pyrophosphate extraction buffer for microcystin analysis of soil samples. It is a popular leavening agent found in baking powders.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
