Insoluble in water. | [Reactivity Profile]
2-ETHYL-2-HEXENAL is an aldehyde. Aldehydes are frequently involved in self-condensation or polymerization reactions. These reactions are exothermic; they are often catalyzed by acid. Aldehydes are readily oxidized to give carboxylic acids. Flammable and/or toxic gases are generated by the combination of aldehydes with azo, diazo compounds, dithiocarbamates, nitrides, and strong reducing agents. Aldehydes can react with air to give first peroxo acids, and ultimately carboxylic acids. These autoxidation reactions are activated by light, catalyzed by salts of transition metals, and are autocatalytic (catalyzed by the products of the reaction). The addition of stabilizers (antioxidants) to shipments of aldehydes retards autoxidation. 2-ETHYL-2-HEXENAL will react with oxidants. | [Health Hazard]
Vapor is irritating. Contact produces skin and eye irritation. | [Hazard]
Toxic by inhalation and ingestion; strong
irritant. | [Potential Exposure]
Those workers involved in organic
synthesis operations and use of this flammable and toxic
aldehyde warning agent.v | [First aid]
Skin Contact: Flood all areas of body that
have contacted the substance with water. Don’t wait to
remove contaminated clothing; do it under the water
stream. Use soap to help assure removal. Isolate contaminated clothing when removed to prevent contact by others.
Eye Contact: Remove any contact lenses at once. Flush
eyes well with copious quantities of water or normal saline
for at least 2030 minutes. Seek medical attention.
Inhalation: Leave contaminated area immediately; breathe
fresh air. Proper respiratory protection must be supplied to
any rescuers. If coughing, difficult breathing or any other
symptoms develop, seek medical attention at once, even if
symptoms develop many hours after exposure. Ingestion: If
convulsions are not present, give a glass or two of water or
milk to dilute the substance. Assure that the person’s airway is unobstructed and contact a hospital or poison center
immediately for advice on whether or not to induce
vomiting | [Shipping]

Hazard Class: 3; Labels: 3-Flammable liquid,
6.1-Poisonous materials, Technical Name Required | [Incompatibilities]
Aldehydes are frequently involved in
self-condensation or polymerization reactions. These reactions are exothermic; they are often catalyzed by acid.
Aldehydes are readily oxidized to give carboxylic acids.
Flammable and/or toxic gases are generated by the combination of aldehydes with azo, diazo compounds, dithiocarbamates, nitrides, and strong reducing agents. Aldehydes
can react with air to give first peroxo acids, and ultimately
carboxylic acids. These autoxidation reactions are activated
by light, catalyzed by salts of transition metals, and are
autocatalytic (catalyzed by the products of the reaction).
The addition of stabilizers (antioxidants) to shipments
of aldehydes retards autoxidation. Incompatible with
oxidizers (chlorates, nitrates, peroxides, permanganates,
perchlorates, chlorine, bromine, fluorine, etc.); contact may
cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides, caustics,
ammonia, and amines | [Waste Disposal]
Incineration, or dissolve in
flammable solvent and spray into incinerator containing
afterburner | [Definition]
ChEBI: 2-ethyl-2-hexenal is a monounsaturated fatty aldehyde that is hex-2-enal substituted by an ethyl group at position 2. It has a role as a plant metabolite, a human metabolite and a flavouring agent. It is a monounsaturated fatty aldehyde and an enal. | [Synthesis Reference(s)]
