2-phenylethyl alcohol (phenylethyl alcohol, PEA)

Its identity is PubChem’s, CID 6054. No share is given: the one figure in the sources is a single sample’s. Its odour threshold in water is 140 micrograms per kilogram, as measured by a food-chemistry institute’s panel.

PubChem’s computed 3D conformer of 2-phenylethyl alcohol (phenylethyl alcohol, PEA) (CID 6054, conformer 000017A600000002): the shape a computer model gives the molecule, not an experimental structure and not a picture of a real molecule. Ball and stick: 8 carbon, 1 oxygen; the 10 hydrogen atoms are left out for clarity. The balls are drawn smaller than the atoms’ real reach; a double bond is two sticks, side by side.
