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 4.4 hrs at a temperature range of 25°C and pH 7.0, respectively. Thus, based on this half-life value, it can be concluded that the test chemical can be considered to be moderately 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 half-life of the test chemical was determined. The study was performed according to OECD Guideline 111 (Hydrolysis as a Function of pH). The study was performed at temp. 10, 25 and 35°C and pH 4, 7 and 9, respectively. Test chemical hydrolysis was followed by measuring its disappearance as a function of time by an extraction method using gas chromatography with flame ionization detection (GC-FID). The half-life of test chemical at 25 °C was observed to be 0.11, 4.4, and 0.22 hrs at pH 4, 7, and 9, respectively. At 10 °C, the half-life of test chemical was observed to be 0.20 and 0.76 hrs at pH 4 and 9, respectively. At 35°C, the half-life of test chemical was observed to be 0.073 and 0.12 hrs at pH 4 and 9, respectively. Thus, based on the half-life value (4.4 hrs) at temp. 25 °C and pH 7.0, test chemical is considered to be moderately hydrolysable in water.
In an another study, the half-life of the test chemical was determined. Although half-life value of test chemical was not known, but test chemical was reported to be hydrolysable in water after a period of 2 days.
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 4.4 hrs at a temperature range of 25°C and pH 7.0, respectively. Thus, based on this half-life value, it can be concluded that the test chemical can be considered to be moderately 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).
