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.
5 Gases under pressure Not applicable - - - "Liquids" according to GHS definition.

A flash point of 24 degrees C [closed cup] (GESTIS (Access on Dec. 2011); MSDS (Sigma-Aldrich) (Access on Dec. 2011)), which is >= 23 degrees C and <= 60 degrees C, corresponds to Category 3.
7 Flammable solids Not applicable - - - "Liquids" according to GHS definition.
8 Self-reactive substances and mixtures Classification not possible - - - There is a chemical group present in the molecule associated with a self-reactive property (strained ring: epoxy group), but the classification is not possible due to no data.
9 Pyrophoric liquids Classification not possible - - - No data.
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 does not contain fluorine or chlorine but contains oxygen which is not chemically bonded to elements other than carbon or hydrogen.
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.

From an LD50 value of 1090 micro L/kg (1053 mg/kg) for rats (RTECS (1997): original literature American Industrial Hygiene Association Journal. 30, 470, 1969) with confirmation of the description in the original literature, it was classified in Category 4.

From an LD50 value of 630 micro L/kg (609 mg/kg) for rabbits (RTECS (1997): original literature American Industrial Hygiene Association Journal. 30, 470, 1969) with confirmation of the description in the original literature, it was classified in Category 3.
1 Acute toxicity (Inhalation: Gases) Not applicable - - - "Liquids" according to GHS definition.
1 Acute toxicity (Inhalation: Vapours) Classification not possible - - - Because the category cannot be determined from LCLo of 2000 ppm/4h for rats in a 4-hour exposure (RTECS (1997): original literature American Industrial Hygiene Association Journal. 30, 470, 1969), the classification is not possible.
Besides, a reference value of gasses as a vapour with hardly included mist was applied because the test concentration (2000 ppm) is lower than 90 % of the saturated vapour pressure concentration (15132 ppm).
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 Not classified - - - On the basis that a micronucleus test using bone marrow after intraperitoneal administration in rats (in vivo somatic cell mutagenicity test) reported a negative (NTP DB (Access on Dec. 2011)), it was classified as "Not classified."
Besides, an Ames test reported mostly a positive result as an in vitro test (NTP DB (Access on Dec. 2011)).
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 - - - No data.
