There are three LD50 values for rats [240 mg/kg (IARC 41 (1986)), 1,300 mg/kg (Environmental Risk Assessment for Chemical Substances vol. 6 (Ministry of the Environment, 2008)), 316-1,000 mg/kg (NTP TR 239 (1982))], one corresponds to Category 3, and two correspond to Category 4. It was classified in Category 4, to which more corresponded. |
1 | Acute toxicity (Dermal) | Not classified |
- |
- | - | It was classified as "Not classified" in the Classification JIS (corresponding to Category 5 in UN GHS classification) based on an LD50 value of 3,309 mg/kg for rabbits (IARC 41 (1986)). |

It was classified in Category 2 based on an LC50 value of 350 ppm by 8-hour exposure of rats (converted 4-hour equivalent value: 495 ppm) (HSDB (2003)). Besides, because LC50 was lower than 90% of the saturated vapour pressure concentration (1118 ppm), a reference value of gasses was applied. |
1 | Acute toxicity (Inhalation: Dusts and mists) | Not classified |
- |
- | - | It was classified as "Not classified" based on an LC50 value of 12.8 mg/L by 4-hour exposure of rats (HSDB (2003)). Besides, because LC50 was higher than the saturated vapour pressure concentration (7.96 mg/L), the reference value of a mist was applied. |
2 | Skin corrosion/irritation | Not classified |
- |
- | - | There was little irritation after a non-occlusive application to the rabbit skin, and there was no response even after 20 applications on the auricle. However, moderate scaliness was produced after 20 applications to the abdomen by the poultice technique, and it is described that this substance is minimally irritating to the skin from the above data (PATTY (5th, 2001)). Therefore, it was classified as "Not classified." |
3 | Serious eye damage/eye irritation | Classification not possible |
- |
- | - | It is described that this substance is minimally irritating to the rabbit eye (PATTY (5th, 2001)), but because data details are unknown, it was classified as "Classification not possible." |
4 | Respiratory sensitization | Classification not possible |
- |
- | - | No data available. |
4 | Skin sensitization | Classification not possible |
- |
- | - | No data available. |
5 | Germ cell mutagenicity | Not classified |
- |
- | - | It was classified as "Not classified" based on a negative result in a chromosomal aberration test with bone marrow after intraperitoneal administration to mice (in vivo somatic cell mutagenicity test) (NTP DB (Access on Jan. 2012)). Besides, both a sister chromatid exchange test with bone marrow after intraperitoneal administration to mice and a DNA synthesis test with mouse hepatocytes (in vivo somatic cell genotoxicity test) were reported to be negative (NTP DB (Access on Jan. 2012)). On the other hand, as for in vitro tests, it is reported that it was positive in all of an Ames test, a mouse lymphoma test, and a chromosomal aberration test with CHO cells (NTP DB (Access on Jan. 2012), IARC 41 (1986)). |
6 | Carcinogenicity | Classification not possible |
- |
- | - | It was classified as "Classification not possible" because IARC classified it in Group 3 for carcinogenicity (IARC 71 (1999)). Besides, in carcinogenicity tests by 2-year oral administration to rats and mice, in rats, the incidence of any tumors was not higher than in the control group, and carcinogenicity was not observed. However, in mice, it is reported that there were increased incidences of alveolar/bronchiolar adenoma in males and females and hepatocellular carcinoma in males, there was the occurrence of squamous cell papilloma or carcinoma in the stomach or forestomach, a rare tumor, in females, and carcinogenicity was found (NTP TR 239 (1982)). |
7 | Reproductive toxicity | Not classified |
- |
- | - | It is reported that in a three-generation breeding test by feeding to rats, there were no reproductive or developmental effects (Environmental Risk Assessment for Chemical Substances vol. 6 (Ministry of the Environment, 2008)). And it is reported that in a developmental toxicity test with pregnant rats or rabbits orally dosed during the organogenesis period, reduced weight gain or a decrease in food consumption occurred in maternal animals in the high dose group, but no other effects were observed in maternal animals or fetuses in either animal species (Environmental Risk Assessment for Chemical Substances vol. 6 (Ministry of the Environment, 2008)). Because no adverse effects on sexual function and fertility or adverse effects on the development of fetuses were found in the three-generation breeding test and the developmental toxicity test, it was classified as "Not classified." |

The lowest dose at which deaths were observed in rats after 8-hour inhalation exposure was 175 ppm (converted 4-hour equivalent value: 1.732 mg/L), and the hepatic and renal injury was also described (IARC 41 (1986)). In another test with rats, 6-hour inhalation exposure (converted 4-hour equivalent value: 6.0 mg/L) to 700 ppm caused deaths, and necropsy revealed slight lung irritation and moderate to severe hepatic damage, and after 6 to 8-hour exposure to 350 ppm (converted 4-hour equivalent value: 3.0-3.46 mg/L), lung congestion and liver necrosis were reported (PATTY (5th, 2001)). Because severe effects on the liver were commonly observed in the above two inhalation exposure tests, and the test concentrations corresponded to the guidance values for Category 1, it was classified in Category 1 (liver). And because slight lung irritation (lung congestion at the lethal dose) was reported, and irritation of the nose and lung was described as effects after inhalation exposure (IARC 41 (1986)), it was classified in Category 3 (respiratory tract irritation). |
9 | Specific target organ toxicity - Repeated exposure | Classification not possible |
- |
- | - | It is reported that pneumonitis occurred at or above 50 mg/kg/day in a 13-week repeated oral administration test with mice (NTP TR 239 (1982)), however, there were no reports on lung changes in other mouse tests by 3-month or 2-year oral administration (Environmental Risk Assessment for Chemical Substances vol. 6 (Ministry of the Environment, 2008)). Therefore, the lung findings were considered inadequate for the rationale for classification, and it was classified as "Classification not possible." And in 3-month or 2-year oral administration tests with rats or mice, changes in hematological parameters, blood effects such as hemosiderin deposit and extramedullary hematopoiesis in the spleen, and hepatic effects such as elevated hepatic enzymes and hepatocellular necrosis were reported (Environmental Risk Assessment for Chemical Substances vol. 6 (Ministry of the Environment, 2008)), but these were not adopted because they were findings at the doses all exceeding the guidance value range. |
