Description

CAS: 868-14-4 | C4H5KO6 | 188.18 g/mol

Potassium hydrogen L-tartrate is used for stabilizing egg whites, whipped cream and for anti-caking and thickening. It is utilized for the prevention of crystallization of sugar syrups and reduces the discoloration of boiled vegetables. It is an active component in baking powder. It is used in household items in association with lemon juice or white vinegar to clean metals such as brass, aluminum and copper. Furthermore, it serves as a primary reference standard for a pH buffer.

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.
