Rationale for the classification
1 Explosives Not applicable - - - There are no chemical groups associated with explosive properties present in the molecule.
2 Flammable gases (including chemically unstable gases) Not applicable - - - "Solids" according to GHS definition.
3 Aerosols Not applicable - - - Not an aerosol product.
4 Oxidizing gases Not applicable - - - "Solids" according to GHS definition.
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 - - - 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 Classification not possible - - - No data.
11 Self-heating substances and mixtures Classification not possible - - - No established test method suitable for a solid with a melting point of 140 degrees C or lower.
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).
13 Oxidizing liquids Not applicable - - - "Solids" according to GHS definition.
14 Oxidizing solids Not applicable - - - It contains oxygen and bromine which are not chemically bonded to elements other than carbon or hydrogen.
15 Organic peroxides Not applicable - - - An organic compound that does not contain -O-O- structure.
16 Corrosive to metals Classification not possible - - - Because a solid with a melting point of 55 degrees C or lower has no data, the classification is not possible.

From an LD50 value of 50 mg/kg for rats (HSDB (2009)), it was classified in Category 2.
1 Acute toxicity (Dermal) Not classified - - - From an LD50 value of > 2000 mg/kg for rabbits (CICAD 66 (2005)), it was classified as "Not classified" in JIS classification (Category 5 or "Not classified" in UN GHS classification).
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.

P362
A test applied undiluted this substance to rabbit skin for 24 hours reported slight hyperemia with moderate edema (CICAD 66 (2005)). And there is the information that it is irritating to the skin (HSDB (2009)).
Therefore it was classified in Category 2.
3 Serious eye damage/eye irritation Category 2A

Warning
H319
P305+P351+P338
P337+P313
P264
P280
Extensive conjunctival and corneal damage were observed after undiluted this substance application in a test using rabbits.
And extensive conjunctival irritation with moderate corneal damage was reported in the application of 10 % solution. (CICAD 66 (2005))
From the results, it was classified in Category 2A.
4 Respiratory sensitization Classification not possible - - - No data.
4 Skin sensitization Classification not possible - - - No data.
5 Germ cell mutagenicity Classification not possible - - - No data.
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 - - - It was classified as "Classification not possible" because details of the information that "it is irritating to respiratory system" (HSDB (2009)) are unknown due to no further description.
9 Specific target organ toxicity - Repeated exposure Classification not possible - - - No data.
10 Aspiration hazard Classification not possible - - - No data.

It was classified in Category 2 from 72-hour ErC50 = 1.1 mg/L for algae (Pseudokirchneriella subcapitata) (Results of Eco-toxicity tests of chemicals conducted by Ministry of the Environment in Japan, 2005).
11 Hazardous to the aquatic environment (Long-term) Category 1

Warning
H410
P273
P391
P501
If chronic toxicity data are used, then it is classified in Category 1 from non-rapidly degradable (a degradation rate by BOD: 0 % (the existing chemicals survey program, 2002)) and 72-hour NOEC = 0.10 mg/L for algae (Pseudokirchneriella subcapitata) (Results of Eco-toxicity tests of chemicals conducted by Ministry of the Environment in Japan, 2005).
If acute toxicity data are used for trophic levels for which chronic toxicity data are lacking, then it is classified in Category 2 from non-rapidly degradable (a degradation rate by BOD: 0 % (the existing chemicals survey program, 2002)) and 48-hour EC50 = 2.1 mg/L for crustacea (Daphnia magna) (Results of Eco-toxicity tests of chemicals conducted by Ministry of the Environment in Japan, 2005).
It was classified in Category 1 by a comparison between the above results.
12 Hazardous to the ozone layer Classification not possible - - - This substance is not listed in Annexes to the Montreal Protocol.
