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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information
The following data were taken into consideration for PNEC derivation:
| Molecular weight | 153.2 |
| log Kow | -2.99 |
| melting point (°C) | |
| boiling point (°C) | 124 |
| water solubility | > 1000 g/L at 20°C |
| vapour pressure | 0.048 Pa at 25°C |
| Short-term toxicity to fish | 96 h LC50 >100 mg/L |
| Short-term toxicity to daphnia | 48 h EC50 = 63.53 mg/L |
| Long-term toxicity to daphnia | 21 d NOEC = 5.3 mg/L |
| Short-term toxicity to alga | 72 h ErC50= 6.8 mg/L |
| Long-term toxicity to alga | 72 h NOEC = 0.73 mg/L |
Conclusion on classification
Based on the available ecotoxicity data and the substances being readily biodegradable, no classification for acute environmental effects is required. However, the substances are classified as Aquatic Chronic 3 based on the NOEC obtained for algae.
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.
