Potassium acetate is used as deicer to remove snow and ice from the surface and considered as a replacement for calcium chloride or magnesium chloride. It is used as a food additive, as a buffer in biological research, as an extinguishing agent used in class K fire extinguishers and as a catalyst to produce polyurethane polymers. It is utilized for the precipitation of dodecyl sulfate bound proteins, thereby removal of proteins from DNA. It plays an important role in preserving tissues, fixation and mummification.

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.

Applications
Potassium acetate is used as deicer to remove snow and ice from the surface and considered as a replacement for calcium chloride or magnesium chloride. It is used as a food additive, as a buffer in biological research, as an extinguishing agent used in class K fire extinguishers and as a catalyst to produce polyurethane polymers. It is utilized for the precipitation of dodecyl sulfate bound proteins, thereby removal of proteins from DNA. It plays an important role in preserving tissues, fixation and mummification.
