Since its flash point reported 26 degC (closed-cup) (HSDB (2009)) is >= 23 degC and <= 60 degC, the substance corresponds to Category 3.
7 Flammable solids Not applicable - - - - Liquid (GHS definition)
8 Self-reactive substances and mixtures Not applicable - - - - There are no chemical groups present in the molecule associated with explosive or self-reactive properties.
9 Pyrophoric liquids Classification not possible - - - - No data available.
10 Pyrophoric solids Not applicable - - - - Liquid (GHS definition)
11 Self-heating substances and mixtures Classification not possible - - - - Test methods applicable to liquid substances are not available.
12 Substances and mixtures which, in contact with water, emit flammable gases Not applicable - - - - The chemical structure of the substance does not contain metals or metalloids (B, Si, P, Ge, As, Se, Sn, Sb, Te, Bi, Po, At).
13 Oxidizing liquids Not applicable - - - - The substance is an organic compound containing oxygen which is chemically bonded only to carbon or hydrogen.
14 Oxidizing solids Not applicable - - - - Liquid (GHS definition)
15 Organic peroxides Not applicable - - - - Organic compounds containing no bivalent -O-O- structure.
16 Corrosive to metals Classification not possible - - - - No data available.

HEALTH HAZARDS
Hazard class Classification Symbol Signal word Hazard statement Precautionary statement Rationale for the classification
1 Acute toxicity (Oral) Classification not possible - - - - No data available.
1 Acute toxicity (Dermal) Classification not possible - - - - Insufficient data were available. The rat LD50 value of 3100 mg/kg (RTECS (2003)) was documented from the "List 3" information source designated in the GHS classification guidance for the Japanese government.
1 Acute toxicity (Inhalation: Gases) Not applicable - - - - Liquid (GHS definition)
1 Acute toxicity (Inhalation: Vapours) Classification not possible - - - - The rat LC0 value of 1470 ppm (PATTY, 5th (2001)) and LCLo value of 3600 ppm (PIM 981 (2001)) were documented. Since these values did not provide the basis for classification, the substance was classified as "Classification not possible". The toxicity values are lower than 90% of the saturated vapor pressure concentration (10432.9 ppm), the criterion values for gas were adopted for the classification.
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 - - - - No data available.
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 - - - - It was reported that the rats exposed to 5 mg/L for 5 hours by inhalation caused ataxia, mild hypoxemia and mild hypercapnia, and that these signs were in some extent similar to those caused by ethanol exposure (PIM 981 (2001)). Classification was, however, not possible due to lack of sufficient data.
9 Specific target organ toxicity - Repeated exposure Category 2 (kidney) Warning H373: May cause damage to organs through prolonged or repeated exposure (kidney) P260: Do not breathe dust/fume/gas/mist/vapours/spray.
P314: Get medical advice/attention if you feel unwell.
P501: Dispose of contents/container to ...
In the 13-week inhalation toxicity study with rats (as vapor, 6 hrs/day, 5 days/week), clinical signs such as ataxia and lacrimation were observed only in the high dose groups (5.0 mg/L). Histopathological changes were observed in the kidneys in males at the mid dose (1.0 mg/L) or higher, and the lesions consisted of tubular regeneration in the cortex and outer zone of medulla frequently with epithelial necrosis. In the high dose group, proteinaceous casts in the outer zone of medulla were also observed (PATTY, 5th (2001)). Since the mid dose (1.0 mg/L) corresponded to Category 2 within the guidance values, the substance was classified as Category 2 (kidney).
10 Aspiration hazard Classification not possible - - - - No data available.

ENVIRONMENTAL HAZARDS
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-EC50 = 257.7 mg/L for algae (Ankistrodesmus falcatus) (HSDB, 2009).
11 Hazardous to the aquatic environment (Long-term) Not classified - - - - Classified as "Not classified" since its acute toxicity is "Not Classified" and it is not non-water soluble (water solubility = 23700 mg/L (PHYSPROP Database, 2011)).
12 Hazardous to the ozone layer Classification not possible - - - - This substance is not listed in Annexes to the Montreal Protocol.
