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. |
