5 Gases under pressure Not applicable - - - - Solid (GHS definition)
6 Flammable liquids Not applicable - - - - Solid (GHS definition)
7 Flammable solids Classification not possible - - - - No data available.
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 - - - - Solid (GHS definition)
10 Pyrophoric solids Classification not possible - - - - No data available.
11 Self-heating substances and mixtures Classification not possible - - - - Test methods applicable to solid (melting point <= 140 degC) substances are not available.
12 Substances and mixtures which, in contact with water, emit flammable gases Not applicable - - - - The chemical structure of the substance does not contain metals or metalloids (B, Si, P, Ge, As, Se, Sn, Sb, Te, Bi, Po, At).
13 Oxidizing liquids Not applicable - - - - Solid (GHS definition)
14 Oxidizing solids Not applicable - - - - Organic compounds containing no oxygen, fluorine or chlorine.
15 Organic peroxides Not applicable - - - - Organic compounds containing no bivalent -O-O- structure.
16 Corrosive to metals Classification not possible - - - - The substance is a solid and its melting point is less than 55 degC, but classification is not possible due to lack of additional data.

HEALTH HAZARDS
Hazard class Classification Symbol Signal word Hazard statement Precautionary statement Rationale for the classification
1 Acute toxicity （Oral） Category 4 Warning H302: Harmful if swallowed P301+P312: IF SWALLOWED: Call a POISON CENTER or doctor/physician if you feel unwell.
P264: Wash ... thoroughly after handling.
P270: Do not eat, drink or smoke when using this product.
P330: Rinse mouth.
P501: Dispose of contents/container to ... 		Based on the description that 500 mg/kg administration for two rats caused no mortality, but 1000 mg/kg administration caused deaths in 2 of 3 rats (RTECS (2010), original literature: HPV361 U.S. Environmental Protection Agency; High Production Volume Challenge; Pyridine and Pyridine Derivatives Category. pdf (2003)), the LD50 value was estimated to be > 300 mg/kg and <= 2000 mg/kg. Thus, the substance was classified as Category 4.
1 Acute toxicity （Dermal） Classification not possible - - - - No data available.
1 Acute toxicity （Inhalation: Gases） Not applicable - - - - Solid (GHS definition)
1 Acute toxicity （Inhalation: Vapours） Classification not possible - - - - No data available.
1 Acute toxicity （Inhalation: Dusts and mists） Classification not possible - - - - No data available.
2 Skin corrosion/irritation Classification not possible - - - - No data available.
3 Serious eye damage/eye irritation Classification not possible - - - - No data available.
4 Respiratory sensitization Classification not possible - - - - No data available.
4 Skin sensitization Classification not possible - - - - No data available.
5 Germ cell mutagenicity Classification not possible - - - - No data available.
6 Carcinogenicity Classification not possible - - - - No data available.
7 Reproductive toxicity Classification not possible - - - - No data available.
8 Specific target organ toxicity - Single exposure Classification not possible - - - - No data available.
9 Specific target organ toxicity - Repeated exposure Classification not possible - - - - No data available.
10 Aspiration hazard Classification not possible - - - - No data available.

ENVIRONMENTAL HAZARDS
Hazard class Classification Symbol Signal word Hazard statement Precautionary statement Rationale for the classification
11 Hazardous to the aquatic environment （Acute） Not classified - - - - Classified as "Not classified" from its 96h-LC50 = 726 mg/L for fish (Pimephales promelas) (AQUIRE, 2011).
11 Hazardous to the aquatic environment （Long-term） Not classified - - - - Classified as "Not classified" since its acute toxicity is "Not Classified" and it is not non-water soluble (water solubility = 25.5 g/L (PHYSPROP Database, 2011)).
12 Hazardous to the ozone layer Classification not possible - - - - This substance is not listed in Annexes to the Montreal Protocol.
