Hydrolysis
Administrative data
Link to relevant study record(s)
- Endpoint:
- hydrolysis
- Type of information:
- read-across from supporting substance (structural analogue or surrogate)
- Adequacy of study:
- weight of evidence
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- data from handbook or collection of data
- Remarks:
- experimental data of read across substances
- Justification for type of information:
- Data for the target chemical is summarized based on the structurally similar read across chemicals
- Reason / purpose for cross-reference:
- read-across source
- Reason / purpose for cross-reference:
- read-across source
- Qualifier:
- according to guideline
- Guideline:
- other: as mentioned below
- Principles of method if other than guideline:
- WoE report is based on two hydrolysis studies as-
WoE-2. and WoE-3. - GLP compliance:
- not specified
- Radiolabelling:
- not specified
- Analytical monitoring:
- not specified
- Positive controls:
- not specified
- Negative controls:
- not specified
- Transformation products:
- not specified
- Remarks on result:
- other: 3.Test chemical was reported to be stable in water.
- Validity criteria fulfilled:
- not specified
- Conclusions:
- On the basis of the experimental studies of the structurally and functionally similar read across chemical and applying the weight of evidence approach, it can be concluded that the test chemical is not hydrolysable in water.
- Executive summary:
On the basis of the data available for the structurally and functionally similar read across chemical, the hydrolysis of the test chemical has been determined. Test chemical does not contain the functional group that hydrolyze in water. For hydrolysis to occur, the only reactivity in water would involve desulfonation of the aromatic sulfonic acid or its corresponding sulfonic acid salt and in aqueous acid (sulfuric acid), aromatic sulfonic acids desulfonate at temperatures of 100 to 175 deg C. Although these conditions would not typically encountered in the environment, it was reported that the test chemical is stable in water.
Thus, based on the available information, it can be concluded that the test chemical is not hydrolysable in water.
