Description of key information
A study was carried out according to OECD Guideline 111 (hydrolysis in function of pH). In the course of the preliminary test, the test item was found to be hydrolytically stable at
50°C at pH 4 (<10% hydrolysis after 5 days), whereas full hydrolysis (100%) was noted at pH 7 and 9 at 50°C. Therefore, further testing was necessary at pH 7 at 40°C and at pH 9 at 30°C and 40°C. At pH 7, the half-life times were 9.43 h at 40°C and 2.05 h at 50°C; at pH 9, t1/2 were 1.04 h at 30°C and 0.98 h at 40°C.
In conclusion, the extrapolated half-life times were as follows:
- pH 4 at 25°C: > one year (> 8760 hours)
- pH 7 at 25°C: 4.9 days (118 hours)
- pH 9 at 30°C: 1.04 hours

Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
