It correspond to Category 3 from a flash point of 27 deg C [closed-cup] (MSDS (Sigma-Aldrich) (Access on Sep. 2012)) >= 23 deg C and <= 60 deg C.
7 Flammable solids Not applicable
-
-
- - Liquid (GHS definition)
8 Self-reactive substances and mixtures Classification not possible
-
-

Rationale for the classification
1 Acute toxicity (Oral) Classification not possible
-
-
- - Data are lacking. Besides, it is described in List 3 information that an LD50 value was 8,549 mg/kg for mice (RTECS (2012)), but the details are unknown.
1 Acute toxicity (Dermal) Classification not possible
-
-
- - No data available.
1 Acute toxicity (Inhalation: Gases) Not applicable
-
-
- - Liquid (GHS definition)
1 Acute toxicity (Inhalation: Vapours) Classification not possible
-
-
- - No data available.
1 Acute toxicity (Inhalation: Dusts and mists) Classification not possible
-
-
- - No data available.
2 Skin corrosion/irritation Classification not possible
-
-
- - No data available.
3 Serious eye damage/eye irritation Classification not possible
-
-
- - No data available.
4 Respiratory sensitization Classification not possible
-
-
- - No data available.
4 Skin sensitization Classification not possible
-
-
- - No data available.
5 Germ cell mutagenicity Classification not possible
-
-
- - The classification is not possible due to no in vivo test data. Besides, as for in vitro tests, it is reported that it was negative in an Ames test (OECD TG471, GLP) and positive in a chromosomal aberration test with CHL cells (OECD TG473, GLP) (JECDB (Access on Sep. 2012)).
6 Carcinogenicity Classification not possible
-
-
- - No data available.
7 Reproductive toxicity Classification not possible
-
-
- - No data available.
8 Specific target organ toxicity - Single exposure Classification not possible
-
-
- - No data available.
9 Specific target organ toxicity - Repeated exposure Classification not possible
-
-
- - In a 28-day repeated oral administration test with rats (doses: 0, 20, 100, 500 mg/kg/day) (GLP), pathological changes caused by the administration of the test substance occurred in the liver and kidney in the groups at or above 100 mg/kg/day (converted guidance value: 31 mg/kg/day), and centrilobular hypertrophy of hepatocytes in the liver, and increased hyaline droplets and basophilic changes (as regenerative changes) in the proximal tubular epithelium in the kidney in males were observed (JECDB (Access on Sep. 2012)). Concerning the results, it is described that liver findings were considered to be adaptive phenomena that were generally found when drug-metabolizing enzymes were induced by the administration of various drugs, and kidney findings were changes specific to alpha 2-microglobulin nephropathy, which specifically occurred in male rats, not applicable to humans (JECDB (Access on Sep. 2012)). From the above, no adverse effects were seen at the high dose of 500 mg/kg/day (converted guidance value: 155 mg/kg/day) above the guidance value range, therefore it corresponds to "Not classified" in the oral route. However, due to no data in the other routes, it was classified as "Classification not possible" in this hazard class.
10 Aspiration hazard Classification not possible
-
-
- - No data available.
