Description of key information
Hydrolysis: The substance was highly unstable with a half-life in the order of minutes under test conditions. Instability increased as temperature and pH increased.
Key value for chemical safety assessment
- Half-life for hydrolysis:
- 7 min
- at the temperature of:
- 20 °C
Additional information
Applying the Arrhenius equation, rate constant and half-life of the substance were calculated at 20 °C and pH 4, pH 7 and pH 9. The ln-transformed data of rate constants at the three temperatures of the hydrolysis test were plotted against 1/T (T= t+273.15 °C). The lines were fitted on the data and the rate constants at 20 °C were calculated from the constants and slopes (x coefficient) of regression lines.
The final results are the following:
pH value t1/2, min
4 18
7 7
9 0.32
The substance was highly unstable with a half-life in the order of minutes under test conditions. Instability increased as temperature and pH increased.
