Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 structurally and functionally similar read across chemical and applying the weight of evidence approach, the hydrolysis half-life value of the test chemical can be expected to be ranges from 38 days to 5.5 yrs, at pH range 7-8 and a temperature of 25°C, respectively. Thus, based on this half-life value, it can be concluded that the test chemical is not hydrolysable in water.

Additional information

Hydrolysis

Data available for the structurally and functionally similar read across chemicals has been reviewed to determine the half-life of the test chemical.The studies are as mentioned below:

The base catalyzed second order hydrolysis rate constant and half-life value of test chemical was determined using a structure estimation method. The second order hydrolysis rate constant was determined to be 0.04 L/mol-sec with a corresponding half-life of 5 years and 200 days at pH 7 and 8, respectively. Based on the half-life values, it is concluded that the test chemical is not hydrolysable.

In an another study, the half-life of the test chemical was determined using an estimated pseudo-first order hydrolysis rate constant of 0.00000021/sec.The half-life of test chemical was determined to be 38 days at pH 7 and a temperature of 25°C, respectively. Based on the half-life values, it is concluded that the test chemical is not hydrolysable.

For the test chemical, the base catalyzed second order hydrolysis rate constant of test chemical was determined using a structure estimation method. The second order hydrolysis rate constant of test chemical was determined to be 0.042 L/mol-sec with a half-life value of 5.5 yrs and 200 days at pH 7.0 and 8.0, respectively. Based on the half-life values, it is concluded that the test chemical is not hydrolysable.

On the basis of the experimental studies of the structurally and functionally similar read across chemical and applying the weight of evidence approach, the hydrolysis half-life value of the test chemical can be expected to be ranges from 38 days to 5.5 yrs, at pH range 7-8 and a temperature of 25°C, respectively. Thus, based on this half-life value, it can be concluded that the test chemical is not hydrolysable in water.
