Additional information

One reliable experimental study is available and is selected as key study.

The study (Anadiag, 2012) consisted in the determination of the solubility of one batch of Potassium Trifluoroacetate in water, according to the OECD 105 guideline, and under GLP conditions. 

The solubility of the test item in water following the flask method was 697 g/L in deionized water (pH 6.2) at 25°C. Potassium trifluoroacetate is very soluble in water.
