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.
