Description and Uses
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.
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.
