Chemical Properties

2-Methylbutyl acetate has an apple peel and banana odor.

Chemical Properties

All isomers of amyl acetate are highly flammable, colorless to yellow, watery liquids.

Occurrence

Reported found in apple, apple juice, pear, Scotch whiskey, white wine, Bantu beer, beer, cider, cocoa, fig, grape, melon, pineapple, plum, baked potato, rum, sherry, strawberry, wine, apricot, vinegar, sweet cherry, pimento berry, olive, rye bread, cognac, malt whiskey, rum, nectarines, mountain papaya and mango.

Definition

ChEBI: The acetate ester of 2-methylbutan-1-ol.

Aroma threshold values

Detection: 5 to 11 ppb

Taste threshold values

Taste characteristics at 20 ppm: fruity, sweet, banana, juicy fruit and tutti-frutti note.

Potential Exposure

(n-isomer): Primary irritant (w/o allergic reaction), (sec-isomer) Human Data. Amyl acetates are used as industrial solvents and in the manufacturing and dry-cleaning industry; making artificial fruit-flavoring agents; cements, coated papers, lacquers; in medications as an inflammatory agent; pet repellents, insecticides and miticide. Many other uses.

Shipping

UN1993 Flammable liquids, n.o.s., Hazard Class: 3; Labels: 3-Flammable liquid, Technical Name Required.

Incompatibilities

Vapors may form explosive mixture with air. 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, nitrates. May soften certain plastics.

Toxics Screening Level

The current Initial Threshold Screening Level (ITSL) for 2-methyl butyl acetate is 1100 μg/m3.

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. In accordance with 40CFR165, follow recommendations for the disposal of pesticides and pesticide containers. Must be disposed properly by following package label directions or by contacting your local or federal environmental control agency, or by contacting your regional EPA office.
