Additional information

ADONA is an ammonium salt of a highly fluorinated oxoacid. The molecule dissociates to ammonium and DONA anion in aquatic solution. Decomposition of ADONA by hydrolysis was not significant in all pH buffers tested (pH 4, 7, and 9) after 2.4 hours and 5 days at 50 °C. At pH 4, the % of decomposition was 0 to 0.05; at pH 7, the % of decomposition was 0 to 1.12; at pH 9, the % of decomposition was 0 to 0.22. Therefore, the % decomposition at pH 4, pH 7 and pH 9 is reported to range from 0 to 1.12% after 2.4 hours and 5 days at 50 °C. The half life for ADONA was reported as > 1 year. The test substance is considered to be hydrolytically stable. No other modes of decomposition are relevant in the environment.
