Description of key information

5.1.2 Hydrolysis:Methyl valerate is hydrolytically stable at pH 4 and 7 with half lives between more than 1 year and 322 days at 25°C. The hydrolysis is base-catalyzed as the half life at pH 9 is 8 days.

5.2.1 Biodegradation: The degradation of methyl valerate reached 57% at day 27 of incubation and the pass level could not be reached within 10 days. In accordance with the OECD 301 F, methyl valerate is not readily biodegradable under the conditions of the test, since the criteria for "ready biodegradability" were not met.
