| Hazard class | Classification | Symbol | Signal word | Hazard statement | Precautionary statement | Rationale for the classification | |
|---|---|---|---|---|---|---|---|
| 1 | Acute toxicity （Oral） | Classification not possible | - | - | - | - | Although the rat LD50 of 900mg (EHC (1995); (HSDB (2003)) has been documented, this value is inconsistent with other LD50 values obtained from dermal toxicology tests. Because there were some uncertainties in these data, the substance was classified into "Classification not possible". |
| 1 | Acute toxicity （Dermal） | Classification not possible | - | - | - | - | Although the rat LD50 of 33mg/kg (RTECS (2007)) has been documented, this value is inconsistent with other LD50 values obtained from dermal toxicology tests. Because of some inconsistencies seen in the data, the substance was classified into "Classification not possible". |
| 1 | Acute toxicity （Inhalation: Gases） | Not applicable | - | - | - | - | Solid (GHS definition) |
| 1 | Acute toxicity （Inhalation: Vapours） | Classification not possible | - | - | - | - | No data available. |
