phenylpropanol

Phenylpropanol is an organic compound with the chemical formula C9H12O. It is a substituted propanol, meaning it has a phenyl group attached to the propanol molecule. There are three isomers of phenylpropanol, differing in the position of the hydroxyl group on the propyl chain and the attachment point of the phenyl group. Commonly, it refers to 1-phenylpropan-1-ol or 1-phenylpropan-2-ol.

1-Phenylpropan-1-ol is a chiral alcohol and is found naturally in some essential oils. It has been used as a fragrance ingredient due to its floral and hyacinth-like scent. 1-Phenylpropan-2-ol, also known as methylbenzyl alcohol, is another isomer.

Historically, phenylpropanolamine, a related compound, was widely used as a decongestant and appetite suppressant. However, due to concerns about its association with an increased risk of hemorrhagic stroke, its use in over-the-counter medications has been restricted or banned in many countries. Phenylpropanol itself is not typically used as a medication. Its primary relevance is in its role as a chemical intermediate or as a component in fragrances.
