The relatively pure chemical has a pleasant, mild-green, floral-leafy and somewhat musty odor, almost reminiscent of dry tea leaves. Its woody-herbaceous notes remind of coriander with a citrusy freshness. The odor is distinctly less fatty than that of n-Octanol. The 'technical' grade shows generally the musty note as the chief note, with little or no citrusy or floral or mild odors.
The taste (of the relatively pure material) is slightly musty, green and remotely fruity, berry-like. It shows bitterness in concentrations above 10 ppm.
This secondary alcohol is used extensively in masking odors ('technical grade') or other fragrances for industrial or 'heavy-duty' household purposes. The purer grade material is used in herbaceous perfumes, Fougères, Chypres, etc. to a limited degree.
