HEALTH HAZARDS

Hazard class		Classification	Pictogram Signal word	Hazard statement (code)	Precautionary statement (code)	Rationale for the classification
1	Acute toxicity (Oral)	Category 3	Danger	H301	P301+P310 P264 P270 P321 P330 P405 P501	It was classified in Category 3 based on an LD50 value of 91 mg/kg for rats (RTECS (2006), the original article: National Technical Information Service, OTS0528439).
1	Acute toxicity (Dermal)	Not classified	- -	-	-	It was classified as "Not classified" from an LD50 value of > 5,000 mg/kg for rats (IUCLID (2000)), and an LD50 value of > 2,000 mg/kg for rabbits and no dead animals (IUCLID (2000)).
1	Acute toxicity (Inhalation: Gases)	Not applicable	- -	-	-	Solid (GHS definition)
1	Acute toxicity (Inhalation: Vapours)	Category 1	Danger	H330	P304+P340 P403+P233 P260 P271 P284 P310 P320 P405 P501	It was classified in Category 1 based on LC50 values by 4-hour exposure for rats of > 0.452 mg/L (> 58.8 ppm) for males and 0.338 mg/L (44 ppm) for females (IUCLID (2000)). Besides, because the test concentrations were lower than 90% of the saturated vapour pressure concentration (99 ppm), a reference value of gas was applied as a vapour with little mist.
1	Acute toxicity (Inhalation: Dusts and mists)	Category 4	Warning	H332	P304+P340 P261 P271 P312	It was classified in Category 4 based on an LC50 value of 2.7 mg/L for rats (IUCLID (2000)). Besides, because the test concentration was higher than the saturated vapour pressure concentration (0.77 mg/L), a reference value of dust/mist was applied.
2	Skin corrosion/irritation	Not classified	- -	-	-	It was classified as "Not classified" because it was not irritating in a test by a 4-hour application to the rabbit skin (OECD TG404, GLP-compliant) (IUCLID (2000)), and it was not a primary irritant in another test with rabbits (Federal Hazardous Substance Act, Section 191.11) (IUCLID (2000)).
3	Serious eye damage/eye irritation	Category 1	Danger	H318	P305+P351+P338 P280 P310	In an eye irritation test with rabbits (OECD TG 405, GLP-compliant), it was assessed as irritating, and a warning was issued on the risk of causing serious eye disorders (IUCLID (2000)). And it is reported that corrosivity and extreme irritation were observed 24 hours after the application in another test with rabbits (Federal Hazardous Substance Act, Section 191.12) (IUCLID (2000)). From the above test results, it was classified in Category 1.
4	Respiratory sensitization	Classification not possible	- -	-	-	No data available.
4	Skin sensitization	Classification not possible	- -	-	-	It is reported that it was sensitizing in a maximization test with guinea pigs (OECD TG406, GLP-compliant) (IUCLID (2000)), but the details such as a positive rate are unknown. Therefore, it was classified as "Classification not possible."
5	Germ cell mutagenicity	Classification not possible	- -	-	-	The classification is not possible due to no in vivo test data. Besides, as for in vitro mutagenicity tests, it is reported that it was negative in both an Ames test (OECD TG 471, 472) and a chromosomal aberration test with V79 cells (OECD TG 473) (IUCLID (2000)).
6	Carcinogenicity	Classification not possible	- -	-	-	No data available.
7	Reproductive toxicity	Classification not possible	- -	-	-	No data available.
8	Specific target organ toxicity - Single exposure	Category 3 (Respiratory tract irritation)	Warning	H335	P304+P340 P403+P233 P261 P271 P312 P405 P501	It was classified in Category 3 (respiratory tract irritation) because it is described that this substance is a strong irritant, especially to the eye and mucous membranes, and it is strongly irritating to the mucosa of the nose and throat (HSDB (2002)). Besides, it is reported that decreased locomotor activity, salivation, and diarrhea were observed after oral administration of 50-100 mg/kg to cats, but there were no effects on hematological profile (IUCLID (2000)).
9	Specific target organ toxicity - Repeated exposure	Classification not possible	- -	-	-	It is reported that no deaths or symptoms of poisoning were observed in a test by 14-day oral administration of 100 mg/kg/day (converted guidance value = 15.6 mg/kg/day) to male rats (IUCLID (2000)), but it had only one test dose within the guidance value range, and the test details are unknown. Therefore, it was classified as "Classification not possible."
10	Aspiration hazard	Classification not possible	- -	-	-	No data available.
