Classified into Category 2 since flash point 11 degC (closed-cup) (GESTIS (access on Oct. 2009)) is <23 degC and initial boiling point 113 degC (Ullmanns (E) (6th, 2003)) is >35 degC. The substance is classified into Class 3, PG II in UNRTDG (UN2380).
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 Not classified - - - - The substance does not fall into upper Division 4.2, PG I since it is classified into Class 3, PG II in UNRTDG (UN2380).
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 classified - - - - The substance does not fall into upper Division 4.3 (Substances which in contact with water emit flammable gases) since water solubility is 23300 mg/L (25 degC) (Howard (1997)) though it contains metals (Si) and is judged to be stable against water, further it is classified into Class 3, PG II in UNRTDG (UN2380).
13 Oxidizing liquids Classification not possible - - - - No data available.
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) Not classified - - - - Based on a LD50 value of 2.5 g/kg for rats (PATTY (5th, 2001)), the substance was classified into "Not classified" in JIS Classification (correspond to Category 5 in GHS classification).
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 - - - - Classification not possible due to lack of data. As relevant information, a LC50 value is 4000 ppm/8h (5656 ppm/4h) for rats (PATTY (5th, 2001)).
1 Acute toxicity (Inhalation: Dusts and mists) Classification not possible - - - - No data available.
2 Skin corrosion/irritation Classification not possible - - - - Classification not possible due to lack of data. As information in a document in List 3, there is a report of "mild" irritating in a Draize test where 500 mg of the substance was applied to the skin of rabbits for 24-hour (RTECS (1997)).
3 Serious eye damage/eye irritation Classification not possible - - - - Classification not possible due to lack of data. As information in a document in List 3, there is a report of "mild" irritating in a Draize test where 500 mg of the substance was applied to the eye of rabbits (RTECS (1997)).
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 - - - - No data available.
9 Specific target organ toxicity - Repeated exposure Classification not possible - - - - No data available.
10 Aspiration hazard Classification not possible - - - - No data available.

ENVIRONMENTAL HAZARDS

11 Hazardous to the aquatic environment (Acute) Category 2 - - H401: Toxic to aquatic life P273: Avoid release to the environment.
P501: Dispose of contents/container to ...
Classified into Category 2 from its 48h-EC50 = 1.25 mg/L for Crustacea (Daphnia magna) (AQUIRE, 2010).
11 Hazardous to the aquatic environment (Long-term) Category 2 - H411: Toxic to aquatic life with long lasting effects P273: Avoid release to the environment.
P391: Collect spillage.
P501: Dispose of contents/container to ...
Classified into Category 2 since its acute toxicity is Category 2 and it is not rapidly degradable (BIOWIN).
