Classified into Category 2 since flash point -29 degC (Ullmanns (E) (6th, 2003) and others) is <23 degC and initial boiling point 44 degC (Ullmanns (E) (6th, 2003)) is >35 degC. The substance is classified into Class 3, PG II in UNRTDG (UN2246).
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 "Self-reactive substances and mixtures" from which it is classified into Class 3, PG II in UNRTDG (UN2246) though there are chemical groups (orefin) present in the molecule associated with self-reactive properties.
9 Pyrophoric liquids Not classified - - - - Auto-ignition point is 395 degC (Ullmanns (E) (6th, 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 does not contain oxygen, fluorine or chlorine.
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 - - - - Test methods applicable to liquid (low boiling point) substances are not available.

HEALTH HAZARDS
Hazard class Classification Symbol Signal word Hazard statement Precautionary statement Rationale for the classification
1 Acute toxicity (Oral) Classification not possible - - - - Classification not possible due to lack of data. As relevant information, a LD50 value is 2.14 mL/kg (1650 mg/kg) for rats (RTECS (2004)).
1 Acute toxicity (Dermal) Classification not possible - - - - Classification not possible due to lack of data. As relevant information, a LD50 value is 1.59 mL/kg (1224 mg/kg) for rabbits (RTECS (2004)).
1 Acute toxicity (Inhalation: Gases) Not applicable - - - - Liquid (GHS definition)
1 Acute toxicity (Inhalation: Vapours) Classification not possible - - - - Although there is information that 4/6 rats died following exposure at 16,000 ppm for 4-hour (PATTY (5th, 2001)), classification was not possible since determination of category was impossible. Since the exposure concentration was lower than 90% of saturated vapour pressure concentration (5,000,000 ppm, 25 degC), the substance was determined as "vapour with almost no included mists", and classification criteria for gas was adopted.
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 - - - - No data available.
9 Specific target organ toxicity - Repeated exposure Classification not possible - - - - Based on information that decreased body weight gain was observed at dose level of 8110 ppm/6h/day (22.5 mg/L/6h/day) in a rat 3-week vapour inhalation test (PATTY (5th, 2001)) and that there were no adverse effects at dose level of 1139 ppm/6h/day (3.1 mg/L/6h/day) in a 12-week inhalation test (PATTY (5th, 2001)), the substance corresponds to "Not classified" with inhalation exposure. However, classification was not possible due to lack of data with other exposure routes.
10 Aspiration hazard Classification not possible - - - - No data available.
