Description of key information

For pH 4 and pH 7 no abiotic degradation of the test item was observed in aqueous buffer solutions with acetonitrile as organic solvent additive (30 % v/v). For pH 9 a slight degradation less than 10 % was observed.

Key value for chemical safety assessment

Additional information

The test item is considered to be hydrolytically stable at 50°C at all three pH-values (4, 7, 9) in the different buffer solutions using acetonitrile as solvent additive. It can be assumed that the test item is also stable at 25 °C and no half-life times and hydrolysis rates were calculated.
