Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Key study: Test method according to EU method C.7, GLP study. The test substance rapidly hydrolyses and half-life < 4 minutes at pH 4 and 7 (23ºC) and pH 9 (27ºC).
Key value for chemical safety assessment
- Half-life for hydrolysis:
- 4 min
- at the temperature of:
- 23 °C
Additional information
Key study: A study was performed to assess the hydrolytic behaviour of OS-2200 with respect to pH. Due to the highly reactive nature of the test substance, a modified test was performed based on EU method C.7, Abiotic degradation: Hydrolysis as a function of pH. Hydrolysis was evaluated after inverting the test substance in the buffer at pH 4, 7 and 9. Analysis was performed by gas chromatography. Under test conditions the test substance rapidly hydrolysed and exhibited half-lives significantly less than one day (<ca 4 minutes) at pH 4 and 7 ( 23ºC) and at pH 9 (27º C).
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.
