Natural 2-Methyl-1-butanol Usage And Synthesis


Chemical Properties

clear colorless to very slighlty yellow liquid

Chemical Properties

Amyl alcohols (pentanols) have eight isomers. All are flammable, colorless liquids, except the isomer 2,2- dimethyl-1-propanol, which is a crystalline solid.

Chemical Properties

(+/–)2-Methyl-1-butanol has a cooked, roasted aroma with fruity or alcoholic undernotes.

Occurrence

Reportedly present in over 120 natural food products, including apple, apricot, banana, orange, bilberry, black currant, cranberry, papaya, strawberry, tomato and alcoholic beverages

Uses

2-Methyl-1-butanol is a whiskey-scented amyl alcohol that is naturally present in all fruits wine and beer. 2-Methyl-1-butanol is commercially used as a solvent in paints and oils and as flavorant in many processed foods. 2-Methyl-1-butanol has a characteristic redolence, which is thought to account for its active properties as an attractant for hornets and certain wasps, such as yellowjackets, in traps. As a biochemical active ingredient, it has a non-toxic mode of action – targeted pests are killed through physical entrapment.

Uses

Solvent, organic synthesis (introduction of active amyl group), lubricants, plasticizers, additives for oils and paints.
