7a-ethyldihydro-1H,3H,5H-oxazolo[3,4-c]oxazole

Hydrolysis

Description of key information

The hydrolysis rate for the test substance was determined according to OECD 111 guidelines.

Key value for chemical safety assessment

Half-life for hydrolysis:

1.9 h

at the temperature of:

25 °C

Additional information

The hydrolysis rate for the test material at 20 mg/L decreased as the solution pH increased. At pH 4, rapid hydrolysis occurred, with half-lives less than 0.1 hours at 15C and 25C. At pH 7, the half-lives ranged from 7.9 hours (15C) to 1.9 hours (25C). At pH 9, half-lives ranged from 9.6 hours (15C) to 3.8 hours (25C).
