Potassium pyrophosphate

CAS: 7320-34-5

Potassium pyrophosphate is a salt of pyrophosphoric acid, which is a weak acid with pKa = 2.8. It is used in the laboratory to generate phosphate ions from adenosine triphosphate (ATP) and magnesium ions. This reaction is used for the synthesis of nucleotides. Potassium pyrophosphate also inhibits bacterial growth by binding to an enzyme that is necessary for the synthesis of adenine nucleotide, which is essential for protein synthesis.
