Additional information
Conclusion on classification
CLP Self classification:
Acute Toxicity - Not classified – conclusive although insufficient for classification.
Chronic Toxicity: Chronic 3 – based on an EC50 of 34 mg/L mg/L and not readily degradable.
OZONE DEPLETION: CAS 34455-00-0 is not listed in the Montreal Protocol on Substances that Deplete the Ozone Layer. It does not contain reactive halogens (chlorine or bromine) that could play a role in ozone depletion. CAS 34455-00-0 is not hazardous to the ozone layer.
