Moderately toxic by
ingestion and intraperitoneal routes. Mildly
toxic by inhalation and skin contact. A
flammable liquid when exposed to heat,
flame, or oxidzers. To fight fire, use dry
chemical, CO2, foam, fog. When heated to
decomposition it emits acrid smoke and
irritating fumes. | [Hazardous Substances Data]

| Hazard Information | Back Directory | [General Description]
A colorless liquid with a pleasant fruity odor. Less dense than water. Vapors heavier than air. Flash point 110°F. Used as a solvent and for making other chemicals. | [Reactivity Profile]
Ketones, such as 5-METHYLHEXAN-2-ONE(110-12-3), are reactive with many acids and bases liberating heat and flammable gases (e.g., H2). The amount of heat may be sufficient to start a fire in the unreacted portion of the ketone. Ketones react with reducing agents such as hydrides, alkali metals, and nitrides to produce flammable gas (H2) and heat. Ketones are incompatible with isocyanates, aldehydes, cyanides, peroxides, and anhydrides. They react violently with aldehydes, HNO3, HNO3 + H2O2, and HClO4. | [Air & Water Reactions]
Flammable. Slightly soluble in water. | [Hazard]
Moderate fire risk. Central nervous systemimpairment and upper respiratory tract irritant. | [Health Hazard]
Inhalation or contact with material may irritate or burn skin and eyes. Fire may produce irritating, corrosive and/or toxic gases. Vapors may cause dizziness or suffocation. Runoff from fire control may cause pollution. | [Potential Exposure]
MIAK is used as a solvent for
cellulose esters, acrylics, and vinyl copolymers. | [Fire Hazard]
HIGHLY FLAMMABLE: Will be easily ignited by heat, sparks or flames. Vapors may form explosive mixtures with air. Vapors may travel to source of ignition and flash back. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapor explosion hazard indoors, outdoors or in sewers. Runoff to sewer may create fire or explosion hazard. Containers may explode when heated. Many liquids are lighter than water. | [First aid]
If this chemical gets into the eyes, remove any
contact lenses at once and irrigate immediately for at least
15 minutes, occasionally lifting upper and lower lids. Seek
medical attention immediately. If this chemical contacts the
skin, remove contaminated clothing and wash immediately
with soap and water. Seek medical attention immediately.
If this chemical has been inhaled, remove from exposure,
begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and
CPR if heart action has stopped. Transfer promptly to a medical facility. When this chemical has been swallowed,
get medical attention. Give large quantities of water
and induce vomiting. Do not make an unconscious
person vomit | [Shipping]
UN23025-Methylhexan-2-one, Hazard Class: 3;
Labels: 3-Flammable liquid. | [Incompatibilities]
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, nitrated amines, azo,
diazo, azido compounds, carbamates, organic cyanates.

CLEAR COLOURLESS LIQUID | [Chemical Properties]
MIAK is a colorless liquid with a pleasant,
fruity odor. | [Waste Disposal]
Dissolve or mix the material
with a combustible solvent and burn in a chemical incinerator equipped with an afterburner and scrubber. All
federal, state, and local environmental regulations must be
observed.
| [Application]
Methyl isoamyl ketone (MIAK) is used asa solvent for polymers, cellulose esters, nitrocellulose, cellulose acetatebutyrate, andacrylics, and vinyl copolymers. | [Definition]
ChEBI: 5-methyl-2-hexanone is a ketone. | [Preparation]
5-Methyl-2-hexanone is produced by condensation of acetone with isobutyraldehyde. This reaction may be carried out in one or two steps, in the liquid or in the gas phase. | [storage]
Color Code—Red: Flammability Hazard: Store ina flammable liquid storage area or approved cabinet awayfrom ignition sources and corrosive and reactive materials.Prior to working with this chemical you should be trainedon its proper handling and storage. Before entering confinedspace where this chemical may be present, check to makesure that an explosive concentration does not exist. Store intightly closed containers in a cool, well-ventilated areaaway from oxidizers (such as perchlorates, peroxides, permanganates, chlorates, and nitrates), strong oxidizers (suchas chlorine, bromine, and fluorine), reducing agents, andaldehydes. Sources of ignition, such as smoking and openflames, are prohibited where methyl isoamyl ketone is handled, used, or stored. Metal containers involving the transferof 5 gallons or more of methyl isoamyl ketone should begrounded and bonded. Drums must be equipped with selfclosing valves, pressure vacuum bungs, and flame arresters. | [Toxics Screening Level]
The screening level for Methyl Isoamyl Ketone is 2300 μg/m3 based on 8 hour averaging.
