Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
Methyl pyruvate is very unstable in contact with water and hydrolysis rapidly into pyruvate and methanol. Methanol is readily biodegradable in freshwater based on the results of standard ready tests that show 71.5 – 95 percent removal after 5 and 20 days, respectively (Price et al. 1974; Wagner 1976).
The second hydrolysis product is pyruvate for which no data on biodegradation are available. However, pyruvate can be encymatically reduced by lactate dehydrogenase to produce lactic acid. Both molecules are structural closely related and essentially important for the celluar metabolism. There is an ECHA dessiminated dossier available which proves lactic acid to be readily biodegradable but failing the 10 -day-window criteria.
Based on the assessment of both hydrolysis product, methyl pyruvate is considered to be readily biodegradable (failing 10d-window).
Key value for chemical safety assessment

- readily biodegradable
Additional information
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.
