1 | Acute toxicity (Inhalation: Vapours) | Classification not possible | - | - | - | - | No data available. |
1 | Acute toxicity (Inhalation: Dusts and mists) | Classification not possible | - | - | - | - | Although the rat LC50 value of > 2.06 mg/L/4hrs (RTECS (2008), original literature: Federal Register. (U.S. Government Printing Office, Supt. Of Documents, Washington, DC 20402) V71, 36731, (2006)) was documented, this value did not provide a basis for classification, the substance was classified as "Classification not possible". |

Hazard class | Classification | Symbol | Signal word | Hazard statement | Precautionary statement | Rationale for the classification | |
---|---|---|---|---|---|---|---|
11 | Hazardous to the aquatic environment (Acute) | Not classified | - | - | - | - | Classified as "Not classified" from its 96h-LC50 = 6980 - 9784 mg/L for fish (Brachydanio rerio) (IUCLID, 2000). |
11 | Hazardous to the aquatic environment (Long-term) | Not classified | - | - | - | - | Classified as "Not classified" since it is not non-water soluble (water solubility: 13410 mg/L (PHYSPROP Database, 2011)) and its acute toxicity is "Not classified". |
12 | Hazardous to the ozone layer | Classification not possible | - | - | - | - | This substance is not listed in Annexes to the Montreal Protocol. |
