Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 weight109.147
log Kow-2.99
melting point (°C)-20
boiling point (°C)115
water solubility> 1000 g/L at 20°C
vapour pressure1.13E-03 Pa at 25°C
Short-term toxicity to fish96 h LC50 >100 mg/L
Short-term toxicity to daphnia48h EC50 =45.26 mg/L
Long-term toxicity to daphnia21 d NOEC = 3.8 mg/L
Short-term toxicity to alga72 h EC50 =4.85 mg/L
Long-term toxicity to alga72 h NOEC = 0.52 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.
