Hazard class | Classification |
Symbol Signal word |
Hazard statement | Precautionary statement | Rationale for the classification | |
---|---|---|---|---|---|---|
1 | Explosives | Classification not possible | - | - | - |
This substance is classified in Class 5.2 Subsidiary risk 1 (UN3101 ORGANIC PEROXIDE TYPE B, LIQUIDS) in UNRTDG (16th, 2009) and corresponds to Explosives, but the classification in divisions is not possible due to no detail test data. Besides, the oxygen balance of -233.52 is lower than -200. |
2 | Flammable gases (including chemically unstable gases) | Not applicable | - | - | - | It is a liquid at normal temperatures (MSDS (Sigma-Aldrich) (2001)). |
3 | Aerosols | Not applicable | - | - | - | Not an aerosol product. |
4 | Oxidizing gases | Not applicable | - | - | - | It is a liquid at normal temperatures (MSDS (Sigma-Aldrich) (2001)). |
5 | Gases under pressure | Not applicable | - | - | - | It is a liquid at normal temperatures (MSDS (Sigma-Aldrich) (2001)). |
6 | Flammable liquids | Category 4 |
H227 |
P370+P378 P403+P235 P210 P280 P501 |
A flash point of 68.3 degrees C [closed cup] (MSDS (Sigma-Aldrich), 2001), which is > 60 degrees C and <= 93 degrees C, corresponds to Category 4. | |
7 | Flammable solids | Not applicable | - | - | - | It is a liquid at normal temperatures (MSDS (Sigma-Aldrich) (2001)). |
8 | Self-reactive substances and mixtures | Not applicable | - | - | - | It is classified as organic peroxides. |
9 | Pyrophoric liquids | Classification not possible | - | - | - | No data. |
10 | Pyrophoric solids | Not applicable | - | - | - | It is a liquid at normal temperatures (MSDS (Sigma-Aldrich) (2001)). |
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 | Classification not possible | - | - | - | An organic compound that contains oxygen which is chemically bonded to oxygen atoms mutually other than carbon, but the classification is not possible due to no data. |
14 | Oxidizing solids | Not applicable | - | - | - | It is a liquid at normal temperatures (MSDS (Sigma-Aldrich) (2001)). |
15 | Organic peroxides | Type B |
H241 |
P411+P235 P210 P220 P234 P280 P410 P420 P501 |
It is classified in Class 5.2 (UN3101 ORGANIC PEROXIDE TYPE B, LIQUIDS) in UNRTDG. | |
16 | Corrosive to metals | Classification not possible | - | - | - | No data. |
Hazard class | Classification |
Symbol Signal word |
Hazard statement | Precautionary statement | Rationale for the classification | |
---|---|---|---|---|---|---|
1 | Acute toxicity (Oral) | Not classified | - | - | - | On the basis of an LD50 value of 16653 mg/kg for rats (PATTY (5th, 2001)), it was classified as "Not classified." |
1 | Acute toxicity (Dermal) | Classification not possible | - | - | - | No data. |
1 | Acute toxicity (Inhalation: Gases) | Not applicable | - | - | - | It is a liquid at normal temperatures (MSDS (Sigma-Aldrich) (2001)). |
1 | Acute toxicity (Inhalation: Vapours) | Not classified | - | - | - | A reported LC50 value of > 207.2 mg/L/4h (> 19458 ppm/4h) (PATTY (5th, 2001)) in an unknown matter state without data on vapour pressure corresponds to "Not classified" (Category 5 or "Not classified" in UN GHS classification) from a reference value, if it is "vapour with hardly included mist" or "vapour with included mists." |
1 | Acute toxicity (Inhalation: Dusts and mists) | Not classified | - | - | - | A reported LC50 value of > 207.2 mg/L/4h (PATTY (5th, 2001)) in an unknown matter state without data on vapour pressure corresponds to "Not classified" if it is a mist. |
2 | Skin corrosion/irritation | Classification not possible | - | - | - | It was classified as "Classification not possible" because a test using rats reports "not an irritant" (PATTY (5th, 2001)) details of which are unknown. |
3 | Serious eye damage/eye irritation | Classification not possible | - | - | - | It was classified as "Classification not possible" because a test using rats reports "not an irritant" (PATTY (5th, 2001)) details of which are unknown. |
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 | - | - | - |
Lack of data. Besides, a 4-hour inhalation test, in which concentrations of 207.2 or 20.8 mg/L were exposed to rats, reports no deaths, no changes in an autopsy, and continuing dyspnea for 1 to 7 days. But it was classified as "Classification not possible" due to unknown further details. |
9 | Specific target organ toxicity - Repeated exposure | Classification not possible | - | - | - | No data. |
10 | Aspiration hazard | Classification not possible | - | - | - | No data. |
