Description of key information

One study was identified.  The hydrolysis was determined using Method C.7 (Degradation: Abiotic Degradation: Hydrolysis as a Function of pH) and OECD Guideline No. 111 (the pre-test). GLP was followed. At pH 4, 7 and 9 and 50 °C, a degree of hydrolysis of < 10%  was observed after 5 days. This corresponds with a half-life time at 25°C of > 1 year; the substance is hydrolytically stable at pH 4, 7 and 9.

Key value for chemical safety assessment

Additional information

Samples were held for the following times: 121 hrs at pH9 and 50°C; 122 hrs at pH4 and 50°C; and 120 h at 50°C was at pH7. In each case less than 10% change in the original concentration of substance was observed. It is concluded that the substance is not readily hydrolyzable in water.
