Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Endpoint:
hydrolysis
Type of information:
other: Statement
Adequacy of study:
key study
Study period:
2005
Reliability:
1 (reliable without restriction)
Qualifier:
according to guideline
Guideline:
OECD Guideline 111 (Hydrolysis as a Function of pH)
Qualifier:
according to guideline
Guideline:
EU Method C.7 (Degradation: Abiotic Degradation: Hydrolysis as a Function of pH)
GLP compliance:
yes
Specific details on test material used for the study:
SOURCE OF TEST MATERIAL
- Source and lot/batch number of test material: PR/MPA-4/50
- Purity: 97.8%

STABILITY AND STORAGE CONDITIONS OF TEST MATERIAL
- Storage condition of test material: 15°C – 25°C in a tight, light resistant container protected from moisture
Radiolabelling:
no
Analytical monitoring:
not specified
Preliminary study:
Study was technically not feasible due to the low water solubility of the test substance.
Test performance:
Study was technically not feasible due to the low water solubility of the test substance.
Transformation products:
not measured
Remarks on result:
not determinable
Remarks:
Study was technically not feasible due to the low water solubility of the test substance.
Conclusions:
The solubility of the test item in water is low. The water solubility of the best item was determined to be lower than 0.2 mg/L, which corresponds approximately to the detection limit of the analytical method. An experimental determination of the hydrolysis was therefore not possible. The described method (OECD 111) is only for water soluable substances.
