Hazard statement Precautionary statement Rationale for the classification
1 Explosives Not applicable - - - There are no chemical groups associated with explosive properties present in the molecule.
2 Flammable gases (including chemically unstable gases) Not applicable - - - "Liquids" according to GHS definition.
3 Aerosols Not applicable - - - Not an aerosol product.
4 Oxidizing gases Not applicable - - - "Liquids" according to GHS definition.

There are data on a flash point such as 2 degrees C [open-cup] (HSDB (2002)) and -18 to 21 degrees C [closed-cup] in UNRTDG (UN2050) (IMDG (2008)).
Also, it corresponds to Category 2 due to a boiling point of 104.9 degrees C (Howard (1997)), a flash point of < 23 degrees C, and an initial boiling point of > 35 degrees C.
Besides, it is classified in Class 3PGII in UNRTDG (UN2050).
7 Flammable solids Not applicable - - - "Liquids" according to GHS definition.
8 Self-reactive substances and mixtures Type G - - - There is a chemical group present in the molecule associated with a self-reactive property (unsaturated double bond), but it is classified in Type G because it is classified in Class 3PGII in UNRTDG (UN2050) and it does not correspond to a superior self-reactive property.
9 Pyrophoric liquids Not classified - - - It is conceivable that it does not ignite at normal temperatures from an ignition point of 305 degrees C (HSDB (2002)).
10 Pyrophoric solids Not applicable - - - "Liquids" according to GHS definition.
11 Self-heating substances and mixtures Classification not possible - - - No established test method suitable for liquid substances.
12 Substances and mixtures which, in contact with water, emit flammable gases Not applicable - - - Not containing metals or semimetals (B, Si, P, Ge, As, Se, Sn, Sb, Te, Bi, Po, At).
13 Oxidizing liquids Not applicable - - - An organic compound that does not contain oxygen, fluorine, or chlorine.
14 Oxidizing solids Not applicable - - - "Liquids" according to GHS definition.
15 Organic peroxides Not applicable - - - An organic compound that does not contain -O-O- structure.
16 Corrosive to metals Classification not possible - - - No data.

Hazard statement Precautionary statement Rationale for the classification
1 Acute toxicity (Oral) Classification not possible - - - No data.
1 Acute toxicity (Dermal) Classification not possible - - - No data.
1 Acute toxicity (Inhalation: Gases) Not applicable - - - "Liquids" according to GHS definition.
1 Acute toxicity (Inhalation: Vapours) Classification not possible - - - No data.
1 Acute toxicity (Inhalation: Dusts and mists) Classification not possible - - - No data.
2 Skin corrosion/irritation Classification not possible - - - No data.
3 Serious eye damage/eye irritation Classification not possible - - - No data.
4 Respiratory sensitization Classification not possible - - - No data.
4 Skin sensitization Classification not possible - - - No data.
5 Germ cell mutagenicity Classification not possible - - - No data.
6 Carcinogenicity Classification not possible - - - No data.
7 Reproductive toxicity Classification not possible - - - No data.
8 Specific target organ toxicity - Single exposure Classification not possible - - - No data.
9 Specific target organ toxicity - Repeated exposure Classification not possible - - - No data.
10 Aspiration hazard Classification not possible - - - This substance is a hydrocarbon and has a kinematic viscosity of 3865.8 mm2/s at -106.31 degrees C (166.84K) (HSDB (2002)), but it was classified as "Classification not possible" because kinematic viscosity at 40 degrees C is unknown.
