The classification was based on the LC50 of 1.15 mg/L (217 ppm) for rats, which was obtained in a 4-hour exposure test (IUCLID (2000)). Given that its saturated vapour is 34000 ppm, in relation to the LC50 value of 217 ppm, the test was presumably conducted in a gaseous state. | |

P305+P351+P338: IF IN EYES: Rinse cautiously with water for several minutes. Remove contact lenses, if present and easy to do. Continue rinsing. P280: Wear protective gloves/protective clothing/eye protection/face protection. P310: Immediately call a POISON CENTER or doctor/physician. |
In rabbit tests, the substance was reported to be severely irritating (IUCLID (2000)), and its pH was found to be 11.5 using a 5 g/L aqueous solution. It is classified into Category 1 for skin corrosion / irritation as well. | |
4 | Respiratory sensitization | Classification not possible | - | - | - | - | No data available. |
4 | Skin sensitization | Classification not possible | - | - | - | - | A mouse ear swelling test found that this substance is not sensitizing (IUCLID (2000)). In addition, a patch test involving one person also found that the substance is not sensitizing (IUCLID (2000)). However due to insufficient data available, classification is not possible. |
5 | Germ cell mutagenicity | Not classified | - | - | - | - | The classification is based on negative results obtained in an in vivo mutagenicity test using somatic cells (micronucleus tests using mouse bone marrow cells) (IUCLID (2000)). In addition to this study, in vivo gene toxicity test (inhibition of DNA-synthesis) gave negative results; regarding in vitro tests, Ames test yielded negative results while chromosomal aberration test produced positive results (IUCLID (2000)). |
6 | Carcinogenicity | Classification not possible | - | - | - | - | There is a study report in which mice were given a mixed diet containing the test substance and its nitrite salt for 12 months, as well as mice in other treatment groups receiving a diet supplemented with soybean or ascorbic acid (IUCLID (2000)). However, classification is not possible based on the results of this study. |
7 | Reproductive toxicity | Classification not possible | - | - | - | - | No data available. |
8 | Specific target organ toxicity - Single exposure | Category 1 (respiratory system) | Danger | H370: Causes damage to organs (respiratory system) |

In the inhalation exposure test in which rats were exposed to 0.76-3.91 mg/L concentrations of the substance for 4 hours, surviving rats showed abnormal breathing and sneezing, while decedent rats showed congestion of the lungs and increased lung weights (IUCLID (2000)). The test concentrations fall under Category 1 guidance values. | |
9 | Specific target organ toxicity - Repeated exposure | Classification not possible | - | - | - | - | No data available. |
10 | Aspiration hazard | Classification not possible | - | - | - | - | No data available. |

11 | Hazardous to the aquatic environment (Acute) | Category 2 | - | - | H401: Toxic to aquatic life |
P273: Avoid release to the environment. P501: Dispose of contents/container to ... |
Since its 96-hour EC50 = 1.16 mg/L for algae (Scenedesmus) (IUCLID, 2000), the substance was classified into Category 2. |
11 | Hazardous to the aquatic environment (Long-term) | Not classified | - | - | - | - | Since its classification for acute toxicity is Category 2, and it is rapidly degradable (BOD: 83 and 95%, when the concentration of the test substance is 100 mg/L and following the standardized testing methods that include a 4-week test period and an activated sludge concentration of 30 mg/L (Biodegradation and Bioconcentration of Existing Chemical Substances under the Chemical Substances Control Law, 1991); and log Kow = 2.83 (PHYSPROP Database, 2008)), the substance was classified into the "Not classified" category. |
