Moderately toxic by
ingestion and skin contact. A skin irritant. A
very dangerous fire hazard when exposed to
heat, flame, or oxidizers. Can react
vigorously with oxidizing materials. To fight
fire, use alcohol foam, CO2, dry chemical.
When heated to decomposition it emits
acrid smoke and irritating fumes. See also

623-42-7(Hazardous Substances Data) |
| Hazard Information | Back Directory | [General Description]
A clear colorless liquid. Flash point 57°F. Less dense than water and slightly soluble in water. Hence floats on water. Vapors heavier than air. | [Reactivity Profile]
METHYL BUTYRATE(623-42-7) reacts exothermically with acids to generate alcohols and carboxylic acids. Strong oxidizing acids may cause a reaction that is sufficiently exothermic to ignite the reaction products. Heat is also generated by interaction with basic or caustic solutions. Flammable hydrogen is generated by mixing with alkali metals and hydrides . | [Air & Water Reactions]
Highly flammable. Slightly soluble in water. | [Hazard]
Flammable, dangerous fire risk. | [Health Hazard]
Irritating to the eyes, nose, throat, upper respiratory tract, and skin. | [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. | [Description]
Methyl butyrate, also known as methyl butanoate , is the methyl ester of butyric acid. Like most esters, it has a fruity odor, in this case resembling apples or pineapples. At room temperature, it is a colorless liquid with low solubility in water, upon which it floats to form an oily layer. Although it is flammable, it has a relatively low vapor pressure ( 40 mm Hg at 30°C), so it can be safely handled at room temperature without special safety precautions. | [Chemical Properties]
colourless liquid | [Chemical Properties]
Methyl butyrate has an apple-like odor and a corresponding sweet
taste that is not very powerful. Below 100 ppm, it may have a
banana-pineapple flavor. May be prepared from methyl alcohol
and butyric acid in the presence of concentrated H2S04. | [Chemical Properties]
Methyl butyrate has an apple-like odor and corresponding sweet taste that is not very powerful. Below 100 ppm, methyl
butyrate may have a banana–pineapple flavor | [Occurrence]
Reported found in apple, apricot, orange, grapefruit and tangerine juice, cranberry, blueberry, guava,
grapes, melon, papaya, pineapple, blackberry, strawberry, tomato, blue, cheddar and parmesan cheese, butter, milk, egg, beef,
white wine, coffee, tea, honey, olive, passion fruit, plum, mushroom, starfruit, mango, fig, prickly pear, wood apple, soursop, cherimoya, myrtle berry, kiwifruit, mountain papaya, custard apple, nectarine, naranjilla, spineless monkey orange and

manufacture of artificial rum and fruit essences. | [Uses]
Methyl butyrate is an important raw material and intermediate used in organic synthesis, pharmaceuticals, agrochemicals and dyestuff fields. | [Uses]
Methyl butyrate is used as a solvent for ethylcellulose
and nitrocellulose resins. It is also used in lacquers
and perfumes and in the manufacture of rum and fruit
flavors. | [Application]
Methyl butyrate is an important raw material and intermediate used in organic synthesis, pharmaceuticals, agrochemicals and dyestuff fields. | [Definition]
ChEBI: Methyl butyrate is a fatty acid ester. | [Preparation]
From methyl alcohol and butyric acid in the presence of concentrated H2SO4. | [Production Methods]
Methyl butyrate is produced from methyl alcohol and
butyric acid in the presence of concentrated sulfuric
acid . | [Aroma threshold values]
Detection: 1 to 43 ppb. Aroma characteristics at 1.0%: pungent, ethereal, fruity, fumey and fusel with a
fermented, cultured, creamy undernote. | [Taste threshold values]
Taste characteristics at 10 ppm: fruity and apple-like with a sweet almost buttery, nutty and creamy nuance,
fusel-like, impacting, and estry with a cultured dairy, acidic depth. | [Synthesis Reference(s)]
Tetrahedron Letters, 29, p. 1759, 1988 DOI: 10.1016/S0040-4039(00)82035-3 | [Potential Exposure]
Methyl butyrate, one of the odorous compound present in different types of adhesive (hotmelt, vinyl acetate ethylene, starch, polyvinyl acetate and acrylic) used in food packaging, was identified by GC-O-MS (gas chromatography–mass spectrometry–olfactometry). | [Carcinogenicity]
Not listed by ACGIH, California
Proposition 65, IARC, NTP, or OSHA. | [Purification Methods]
Treat the ester with anhydrous CuSO4, then distil it under dry nitrogen. [Beilstein 2 IV 786.] | [References]

| Questions And Answer | Back Directory | [Aroma]
Very diffusive and penetrating, sweet-ethereal, fruity odor. In extreme dilution reminiscent of Apple peel with a slightly fatty Peachlike undertone.
Sweet, but not very powerful taste in
aqueous media. Apple-like or Banana-Pineapple-like in dilutions below 100 ppm. |
