5 | Gases under pressure | Not applicable | - | - | - | "Solids" according to GHS definition. |
6 | Flammable liquids | Not applicable | - | - | - | "Solids" according to GHS definition. |
7 | Flammable solids | Classification not possible | - | - | - | The Classification is not possible because there are no data based on a prescribed test though there is information that it is “COMBUSTIBLE” (HSDB (2003)). |
8 | Self-reactive substances and mixtures | Not applicable | - | - | - | Containing neither chemical groups related to explosibility nor those related to self-reactivity. |
9 | Pyrophoric liquids | Not applicable | - | - | - | "Solids" according to GHS definition. |
10 | Pyrophoric solids | Classification not possible | - | - | - | The Classification is not possible because there are no data based on a prescribed test though there is information that it is “COMBUSTIBLE” (HSDB (2003)). |
11 | Self-heating substances and mixtures | Classification not possible | - | - | - | No data. |
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). |

1 | Acute toxicity (Oral) | Category 3 |
|
H301 |
P301+P310 P264 P270 P321 P330 P405 P501 |
On the basis of an LD50 value of 70 mg/kg bw for rats (RTECS (1997): original literature; Archives of Toxicology 54, 275, 1983), it was classified in Category 3. |
1 | Acute toxicity (Dermal) | Classification not possible | - | - | - | No data. |
1 | Acute toxicity (Inhalation: Gases) | Not applicable | - | - | - | "Solids" according to GHS definition. |
1 | Acute toxicity (Inhalation: Vapours) | Classification not possible | - | - | - | No data. |
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 | Category 1 |
|
H317 |
P302+P352 P333+P313 P261 P272 P280 P321 P363 P501 |
It was classified in Category 1 due to the conclusion that "Diphenylthiourea is a human and animal skin sensitizer (limited data)" (ECETOC 77 (1999)) and being listed as a sensitizing substance in Contact Dermatitis (Frosch) (4th, 2006). |
5 | Germ cell mutagenicity | Classification not possible | - | - | - |
The Classification is not possible because there are no in vivo test data. Besides, a "Negative" or "Equivocal" result in an Ames test was reported as an in vitro test (NTP DB (Access on Nov. 2010)). |
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. |

11 | Hazardous to the aquatic environment (Acute) | Category 3 | - |
H402 |
P273 P501 |
It was classified in Category 3 from 96-hour LC50 = 18.9mg/L for fish (Pimephales promelas) (AQUIRE, 2012). |
11 | Hazardous to the aquatic environment (Long-term) | Category 3 | - | H412 |
P273 P501 |
Reliable chronic toxicity data were not obtained. It was classified in Category 3 due to lack of rapid degradability (BIOWIN), and acute toxicity Category 3. |
12 | Hazardous to the ozone layer | Classification not possible | - | - | - | This substance is not listed in Annexes to the Montreal Protocol. |
