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. |
6 | Flammable liquids | Category 3 |

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. |

---|---|---|---|---|---|---|
1 | Acute toxicity (Oral) | Category 4 |
H302 |
P301+P312 P264 P270 P330 P501 |
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. | |
1 | Acute toxicity (Dermal) | Category 3 |
H311 |
P302+P352 P280 P312 P322 P361 P363 P405 P501 |
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. |
