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 |
- |
- | - | It is combustible, but the classification is not possible due to no data. |
8 | Self-reactive substances and mixtures | Not applicable |
- |
- | - | There are no chemical groups present in the molecule associated with explosive or self-reactive properties. |
9 | Pyrophoric liquids | Not applicable |
- |
- | - | "Solids" according to GHS definition. |
10 | Pyrophoric solids | Not classified |
- |
- | - | It is estimated that it does not to ignite at normal temperatures from an ignition point of 520 degrees C (GESTIS (Access on September 2015)). |
11 | Self-heating substances and mixtures | Classification not possible |
- |
- | - | Due to no data, the classification is not possible. |
12 | Substances and mixtures which, in contact with water, emit flammable gases | Not classified |
- |
- | - | It is estimated that it does not react vigorously with water because there is the observation result of insoluble in water (HSDB (Access on September 2015)). |
13 | Oxidizing liquids | Not applicable |
- |
- | - | "Solids" according to GHS definition. |
14 | Oxidizing solids | Not applicable |
- |
- | - | It is an inorganic compound that does not contain oxygen or halogens. |

Hazard statement (code) |
Precautionary statement (code) |
Rationale for the classification | |
---|---|---|---|---|---|---|
1 | Acute toxicity (Oral) | Not classified |
- |
- | - | Because a lethal dose of > 2,000 mg/kg and LDLo value of 6,000 mg/kg for rats were reported (Result of the initial environmental risk assessment of chemicals, Vol. 10, Ministry of the Environment in Japan (2012)), it was classified as "Not classified." |
1 | Acute toxicity (Dermal) | Not classified |
- |
- | - | From a reported lethal dose of > 2,000 mg/kg for rats (Result of the initial environmental risk assessment of chemicals, Vol. 10, Ministry of the Environment in Japan (2012)), it was classified as "Not classified." |
1 | Acute toxicity (Inhalation: Gases) | Not applicable |
- |
- | - | "Solids" according to GHS definition. |
1 | Acute toxicity (Inhalation: Vapours) | Not applicable |
- |
- | - | "Solids" according to GHS definition. |
1 | Acute toxicity (Inhalation: Dusts and mists) | Classification not possible |
- |
- | - | The classification is not possible due to lack of data. Besides, the category cannot be determined only from a reported LC50 value (4 hours) of > 2.820 mg/L for rats (Result of the initial environmental risk assessment of chemicals, Vol. 10, Ministry of the Environment in Japan (2012)). A reference value of dust/mists was applied because the test substance is a solid. |
2 | Skin corrosion/irritation | Classification not possible |
- |
- | - | Due to lack of data, the classification is not possible. |
3 | Serious eye damage/eye irritation | Classification not possible |
- |
- | - | Due to lack of data, the classification is not possible. |
4 | Respiratory sensitization | Classification not possible |
- |
- | - | Due to lack of data, the classification is not possible. |
4 | Skin sensitization | Classification not possible |
- |
- | - | The classification is not possible due to lack of data. Besides, in an investigation on workers handling metals, skin reaction caused by molybdenum sulfide (details unknown) were reported in two out of 860 cases (DFGOT vol. 18 (2002)). |
5 | Germ cell mutagenicity | Classification not possible |
- |
- | - | Due to lack of data, the classification is not possible. |
6 | Carcinogenicity | Classification not possible |
- |
- | - | The classification is not possible due to lack of data. Besides, although ACGIH classified soluble molybdenum compounds in A3 in carcinogenicity, the classification was not given to this substance that belongs to an insoluble molybdenum compound (ACGIH (7th, 2003)). |
7 | Reproductive toxicity | Classification not possible |
- |
- | - | This substance that belongs to an insoluble molybdenum compound cannot be classified due to lack of data. |
8 | Specific target organ toxicity - Single exposure | Classification not possible |
- |
- | - | Due to lack of data, the classification is not possible. |
9 | Specific target organ toxicity - Repeated exposure | Classification not possible |
- |
- | - | Due to lack of data, the classification is not possible. |
10 | Aspiration hazard | Classification not possible |
- |
- | - | Due to lack of data, the classification is not possible. |
