| Hazard Information | Back Directory | [Description]
3-Methyl-2-buten-l-ol has a phenolic, metallic odor bearing a
resemblance to iron gallate ink. May be synthesized from isoprene
by hydration via prenyl acetate or by rearrangement of 3-methyll-buten-3-ol. | [Chemical Properties]
3-Methyl-2-buten-1-ol has a phenolic, metallic odor bearing a resemblance to iron gallate ink | [Chemical Properties]
clear colourless to very slightly yellow liquid | [Uses]
3-Methyl-2-buten-1-ol is used as a reagent for protection of carboxylic acids as their 3-methyl-2-buten-1-yl (Prenyl) esters. It is also used in perfumery. | [Definition]
ChEBI: Prenol is an alkenyl alcohol and a member of prenols. | [General Description]
3-Methyl-2-buten-1-ol reacts with nitrosocarbonyl benzene to yield 5-hydroxy-isoxazolidines. It is commonly used as fragrance ingredient. | [Flammability and Explosibility]
