Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Hydrolysis:
On the basis of the experimental studies of the test chemical and applying the weight of evidence approach, the hydrolysis half-life value of the test chemical can be expected to be ranges 7.3 yr, at pH range 7 and 270 days at pH 8 by base catalysed second order hydrolysis rate constant. Thus, based on this half-life value, it can be concluded that the test chemical not hydrolysable in water.
Additional information
Hydrolysis:
Data available for the test chemical has been reviewed from authoritative database (HSDB, 2017) to determine the half-life of hydrolysis as a function of pH. The studies are as mentioned below:
In first weight of evidence study the half-life and base catalyzed second order hydrolysis rate constant was determined using a structure estimation method of the test chemical The second order hydrolysis rate constant was determined to be 0.03L/mol-sec with a corresponding half-lives of 7.3 yrs and 270 days at pH 7 and 8, respectively. Based on the half-life values, it is concluded that the chemical is not hydrolysable.
In another study the test chemical is not expected to undergo hydrolysis in the environment due to the lack of functional groups that hydrolyze under environmental conditions
On the basis of the experimental studies of the test chemical and applying the weight of evidence approach, the hydrolysis half-life value of the test chemical can be expected to be ranges 7.3 yr, at pH range 7 and 270 days at pH 8 by second order hydrolysis rate constant. Thus, based on this half-life value, it can be concluded that the test chemical not hydrolysable in water.
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.
