A flash point of 52 degrees C [closed cup] (Merck (14th, 2006)), which is >= 23 degrees C and <= 60 degrees C, corresponds to Category 3.
Besides, it is classified in Class 3PGIII in UNRTDG (UN2709 butylbenzenes).
7 Flammable solids Not applicable - - - "Liquids" according to GHS definition.
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 classified - - - It is conceivable that it does not ignite at normal temperatures from an autoignition temperature of 420 degrees C (Sax (11th, 2004)).
10 Pyrophoric solids Not applicable - - - "Liquids" according to GHS definition.
11 Self-heating substances and mixtures Classification not possible - - - No established test method suitable for liquid substances.
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 - - - It is an organic compound that does not contain oxygen or halogens.
14 Oxidizing solids Not applicable - - - "Liquids" according to GHS definition.
15 Organic peroxides Not applicable - - - An organic compound that does not contain -O-O- structure.
16 Corrosive to metals Classification not possible - - - No data.

HEALTH HAZARDS

Hazard statement Precautionary statement Rationale for the classification
1 Acute toxicity (Oral) Not classified - - - On the basis of an LD50 value of 2240 mg/kg bw for rats (PATTY (5th, 2001)), it was classified as "Not classified" in JIS classification (corresponding to Category 5 in UN GHS classification).
1 Acute toxicity (Dermal) Classification not possible - - - Because an LD50 value of > 13800 mg/kg bw for rats (GESTIS (Access on Aug. 2011)), which corresponds to "Not classified", is from List 3 and unknown details, it was classified as "Classification not possible."
1 Acute toxicity (Inhalation: Gases) Not applicable - - - "Liquids" 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 Not classified - - - From an MMAS (equivalent to AOI; the maximal value is 110) of 2.0 as an eye irritation score in a test applied 0.1 mL of undiluted solution of this substance to rabbits eyes, in which conjunctiva redness of grade 1 observed 1 day after application disappeared after 2 days (ECETOC 48 (1998)), it was classified as "Not classified."
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 - - - No data.
9 Specific target organ toxicity - Repeated exposure Classification not possible - - - No data.
10 Aspiration hazard Classification not possible - - - No data.
