Description of key information

The substance is hydrolytically stable at pH 7, relatively stable at pH 4 and tends to be hydrolytically unstable in basic environments tested at pH 9.

Key value for chemical safety assessment

Additional information

The hydrolysis properties of the test item FAT 40850/A TE were tested in a valid GLP study in accordance with EU Method C.7. The substance was found to be hydrolytically stable at pH 7 with a predicted half-life >1 year at 25 °C. At pH 4.0, the test item was relatively stable with a half-life time of 109 days at 25°C. The half-life time at pH 9.0 and 25 °C was determined to be 18 days.
