Diamond Hazard Value Description
1 0
Health   1 Exposure would cause irritation with only minor residual injury (e.g. acetone, sodium bromate, potassium chloride)
Flammability   2 Must be moderately heated or exposed to relatively high ambient temperature before ignition can occur and multiple finely divided suspended solids that do not require heating before ignition can occur. Flash point between 37.8 and 93.3 °C (100 and 200 °F). (e.g. diesel fuel, sulfur)
Instability   0 Normally stable, even under fire exposure conditions, and is not reactive with water (e.g. helium,N2)

2-Heptanone Chemical Properties,Uses,Production


2-Heptanone has a characteristic banana, slightly spicy odor2-Heptanone may be prepared by oxidation of methyl n-amyl carbinol; also from n-amyl propionic acid or from ethyl butyl acetat.

Chemical Properties

2-Heptanone has a fruity, spicy, cinnamon, banana, slightly spicy odor.

Chemical Properties

colourless liquid

Chemical Properties

Methyl amyl ketone is a clear colorless liquid with a mild, banana-like odor.

Physical properties

Colorless liquid with a banana-like odor. Can be detected at a concentration of 140 μg/kg (Buttery et al., 1969a). Cometto-Mu?iz et al. (2000) reported nasal pungency threshold concentrations ranging from approximately 195 to 935 ppm. An odor threshold concentration of 6.8 ppbv was reported by Nagata and Takeuchi (1990).


Reported found in clove essential oil, Ceylon cinnamon and rancid coconut oil; also identifed in Ruta Montana Also reported found in banana, lingonberry, loganberry, black currant, guava, grapes, papaya, peach, pear, raspberry, other berries, strawberry jam, asparagus, roasted onion, leek, baked potato, mushroom, clove bud, ginger, blue, cheddar and Swiss cheeses, milk, cream, butter, fsh, meats, hop oil, beer, brandy, rum, malt whiskey, grape wines, cocoa, coffee, tea, peanuts, pecans, walnut, oats, soybeans, coconut oil, olive, passion fruit, mango, fgs, rice, sweet corn, corn tortillas, malt, caviar, shrimp, oysters, crab, crayfsh and mate


Solvent for nitrocellulose lacquers, synthetic flavoring, perfumery.


Methyl amyl ketone is used as a flavoringagent and as a solvent in lacquers andsynthetic resins.


ChEBI: A dialkyl ketone with methyl and pentyl as the alkyl groups.


By oxidation of methyl n-amyl carbinol; also from n-amyl propionic acid or from ethyl butyl acetate.

Aroma threshold values

Detection: 1 ppb to 1.33 ppm; recognition: 2.66 to 3.73 ppm; aroma characteristics at 1.0%: cheesy ketonic, slightly green waxy, banana fruity.

Taste threshold values

Taste characteristics at 20 ppm: cheesy, fruity, coconut, waxy green, creamy, fungal with buttery and brown fruity nuances.

General Description

A clear colorless liquid. Flash point 126°F. Less dense than water and only slightly soluble in water. Hence floats on water. Vapors heavier than air. Density 6.8 lb / gal. Used as a synthetic flavoring and in perfumes.

Air & Water Reactions

Flammable. Slightly soluble in water.

Reactivity Profile

2-Heptanone reacts exothermically with many acids and bases to produce flammable gases (e.g., H2). The heat may be sufficient to start a fire in the unreacted portion. Reacts with reducing agents such as hydrides, alkali metals, and nitrides to produce flammable gas and heat. Incompatible with isocyanates, aldehydes, cyanides, peroxides, and anhydrides. Incompatible with many oxidizing agents including nitric acid, nitric acid/hydrogen peroxide mixture, and perchloric acid. May form peroxides [USCG, 1999].


Moderate fire risk. Toxic by inhalation, skin and eye irritant, narcotic in high concentration.

Health Hazard

Inhalation can cause headache, fatigue, nausea, vomiting, dizziness, stupor, drowsiness, disturbed vision, and unconsciousness. Skin contact can cause moderate irritation, defatting, and dermatitis. Ingestion may cause irritation of lips and mouth, gastro-intestinal irritation, nausea, diarrhea, drowsiness, loss of consciousness, weak and rapid pulse, cold-pale complexion.

Health Hazard

Exposure to methyl amyl ketone causedirritation of mucous membranes, mild tomoderate congestion of the lungs, and narcosis in test animals. A 4-hour exposure to a4000-ppm concentration in air was lethal torats; 1500–2000 ppm produced lung irritation and narcosis. The concentration at whichit produces similar symptoms in humans isnot known.
The oral toxicity of this compound is low.Its irritant action on skin should be low tovery low.
LD50 value, oral (mice): 730 mg/kg.

Fire Hazard

Combustible liquid, flash point (closed cup) 39.9°C (102°F), (open cup) 48.9°C (12°F); vapor density 3.9 (air = 1) vapor pressure 2.6 torr at 20°C (68°F); autoignition temperature 393°C (740°F); fire-extinguishing agent: “alcohol” foam; a water spray may be used to cool below its flash point.
Methyl amyl ketone forms an explosive mixture with air in the range 1.1% [at 66°C (150.8°F)] to 7.9% [at 121°C (249.8°F)] by volume. It can react explosively with strong acids, alkalies, and oxidizing agents.

Safety Profile

Moderately toxic by ingestion. Mildly toxic by inhalation and skin contact. A skin irritant. A flammable liquid when exposed to heat or flame; can react with oxidizing materials. To fight fire, use foam, CO2, dry chemical. When heated to decomposition it emits acrid smoke and fumes. See also KETONES.


Identified as one of 140 volatile constituents in used soybean oils collected from a processing plant that fried various beef, chicken, and veal products (Takeoka et al., 1996). Also identified as a volatile constituent released by fresh coffee beans (Coffea canephora variety Robusta and Coffea arabica) at different stages of ripeness (Mathieu et al., 1998).

Environmental Fate

Biological. Heukelekian and Rand (1955) reported a 10-d BOD value of 0.50 g/g which is 17.8% of the ThOD value of 2.81 g/g.
Chemical/Physical. Atkinson et al. (2000) studied the kinetic and products of the gas-phase reaction of 2-heptanone with OH radicals in purified air at 25 °C and 740 mmHg. A relative rate constant of 1.17 x 10-11 cm3/molecule·sec was calculated for this reaction. Reaction products identified by GC, FTIR, and atmospheric pressure ionization tandem mass spectroscopy were (with respective molar yields): formaldehyde, 0.38; acetaldehyde, λ0.05; propanal, λ0.05; butanal, 0.07; pentanal, 0.09; and molecular weight 175 organic nitrates.
2-Heptanone will not hydrolyze because it does not contain a hydrolyzable functional group. Burns in air releasing carbon monoxide and carbon dioxide.


UN1110 n-Amyl Methyl ketone, Hazard Class: 3; Labels: 3-Flammable liquid.

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.
