2 Flammable gases (including chemically unstable gases) Not applicable - - - "Liquids" according to GHS definition.
3 Aerosols Not applicable - - - Not an aerosol product.
4 Oxidizing gases Not applicable - - - "Liquids" according to GHS definition.
5 Gases under pressure Not applicable - - - "Liquids" according to GHS definition.

A flash point of 3 degreeC [closed cup] (GESTIS (Access on Dec. 2010)) is < 23 degrees C, and bp 760 of 106.2 degrees (Merck (14th, 2006)) is > 35 degrees C, therefore it is classified in Category 2.
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 was classified as "Not classified" because it is conceivable that it does not ignite at normal temperatures from an ignition temperature of 520 degrees C (GESTIS (Access on Dec. 2010)).
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 - - - An organic compound that contains oxygen which is not chemically bonded to elements other than carbon.
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.

Hazard statement Precautionary statement Rationale for the classification
1 Acute toxicity (Oral) Classification not possible - - - Lack of data.
Besides, details of an LD50 value of 610 mg/kg bw for rats (RTECS (2006)) are unknown.
1 Acute toxicity (Dermal) Classification not possible - - - No data.
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 Classification not possible - - - No data.
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.
Besides, this substance having ketone with a composition of no more than 13 carbon atoms is equivalent to Category 2 in UN GHS classification.

ENVIRONMENTAL HAZARDS

Signal word
Hazard statement Precautionary statement Rationale for the classification
11 Hazardous to the aquatic environment (Acute) Category 3 - H402
P273
P501
It was classified in Category 3 from 96-hour LC50 = 87 mg/L for fish (Pimephales promelas) (ECETOC TR91, 2003).
11 Hazardous to the aquatic environment (Long-term) Category 3 - H412
P273
P501
Reliable chronic toxicity data were not obtained.
It was classified in Category 3 due to lack of rapid degradability (BIOWIN), and acute toxicity Category 3.
12 Hazardous to the ozone layer Classification not possible - - - This substance is not listed in Annexes to the Montreal Protocol.
