P501: Dispose of contents/container to ... 		Classified into Category 2 since the substance can be estimated to fall into Category 2 also under closed-cup test method from which flash point -9 degC (open-cup) (MSDG (2006)) is <23 degC and initial boiling point 83 degC (Ullmanns (E) (2003)) is >35 degC, further it is classified into Class 3, PG II in UNRTDG (UN1304).
7 Flammable solids Not applicable - - - - Liquid (GHS definition)
8 Self-reactive substances and mixtures Type G - - - - Classified into Type G since the substance is considered not to fall into upper class of Self-reactive substances and mixtures from which it contains a stabilizer (hydroquinone (Hommel (1996)) and is classified into Class 3, PG II in UNRTDG (UN1304) though there are chemical groups (unsaturated bond) present in the molecule associated with self-reactive properties.
9 Pyrophoric liquids Not classified - - - - Auto-ignition point is 195 degC (Ullmanns (E) (2003)) exceeding 70 degC.
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 (but not fluorine or chlorine) 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） Not classified - - - - Based on a LD50 value of 17.0 mL/kg (12920 mg/kg) for rats (PATTY (5th, 2001)), the substance was classified into "Not classified".
1 Acute toxicity （Dermal） Not classified - - - - Based on a LD50 value of 20 mL/kg (15800 mg/kg) for rabbits (PATTY (5th, 2001)), the substance was classified as "Not classified".
1 Acute toxicity （Inhalation: Gases） Not applicable - - - - Liquid (GHS definition)
1 Acute toxicity （Inhalation: Vapours） Category 4 Warning H332: Harmful if inhaled P304+P340: IF INHALED: Remove victim to fresh air and keep at rest in a position comfortable for breathing.
P261: Avoid breathing dust/fume/gas/mist/vapours/spray.
P271: Use only outdoors or in a well-ventilated area.
P312: Call a POISON CENTER or doctor/physician if you feel unwell. 		Based on a LC50 value of 66.4 mg/L/4h (16205 ppmV) for rats (IUCLID (2000)), the substance was classified into Category 4. Since the test was conducted at lower than 90% of saturated vapour pressure concentration (78289 ppm), the classification criteria for gas was adopted.
1 Acute toxicity （Inhalation: Dusts and mists） Classification not possible - - - - No data available.
2 Skin corrosion/irritation Category 2 Warning H315: Causes skin irritation P302+P352: IF ON SKIN: Wash with plenty of soap and water.
P332+P313: If skin irritation occurs: Get medical advice/attention.
P264: Wash ... thoroughly after handling.
P280: Wear protective gloves/protective clothing/eye protection/face protection.
P321: Specific treatment （see ... on this label）.
P362: Take off contaminated clothing and wash before reuse. 		Based on a result of "irritation" in a rabbit Draize test by occluded dermal application for 2-hour (IUCLID (2000)), the substance was classified into Category 2. Although there is a result of "grade 1 irritating" in another rabbit test (PATTY (5th, 2001)), the result was not used as the basis of classification since the test method was not clear and the test was conducted in an earlier time (1943 - 1948).
3 Serious eye damage/eye irritation Not classified - - - - Based on a result of "not irritating" in a rabbit test (IUCLID (2000)), the substance was classified as "Not classified".
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 - - - - Classification not possible due to lack of data from in vivo mutagenicity tests. From in vitro mutagenicity tests, there are reports of a negative Ames test (OECD TG471), a negative CHO-K1 cell HGPRT assay (OECD TG476) and a negative V79 cells chromosome aberration test (OECD TG473) (IUCLID (2000)).
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.
