l-Octen-3-ol has a powerful, sweet, earthy odor with a strong, herbaceous note reminiscent of lavender-lavandin, rose, and hay. It has a sweet, herbaceous taste. May be prepared from magnesium amyl bromide and acrolein.

Chemical Properties

1-Octen-3-ol has a powerful, sweet, earthy odor with a strong, herbaceous note reminiscent of lavender–lavandin, rose and hay. It has a sweet, herbaceous taste.

Chemical Properties

1-Octen-3-ol may occur in the optically active form. It is found, for example, in lavender oil and is a steam-volatile component of mushrooms. l-Octen-3-ol is a liquid with an intense mushroom, forest–earthy odor that can be prepared by a Grignard reaction from vinylmagnesium bromide and hexanal. It is used in lavender compositions and in mushroom aromas.

Preparation

From magnesium amyl bromide and acrolein.
