Applications
Food additive
Potassium acetate is used as a food additive as a preservative and acidity regulator. In the European Union, it is labeled by the E number E**1; it is also approved for usage in the USA and Australia and New Zealand. Potassium hydrogen diacetate (CAS #********0) with formula KH(OOCCH3)2 is a related food additive with the same E number as potassium acetate.
Medicine and biochemistry
In medicine, potassium acetate is used as part of replacement protocols in the treatment of diabetic ketoacidosis because of its ability to break down into bicarbonate and help neutralize the acidotic state.
In molecular biology, potassium acetate is used to precipitate dodecyl sulfate (DS) and DS-bound proteins, allowing the removal of proteins from DNA. It is also used as a salt for the ethanol precipitation of DNA.
