Products Description of 1-Hexanol CAS#111-27-3
1-Hexanol is a colorless liquid that boils at 157°C and has a density of 0.819. It mixes easily with ethanol, propylene glycol, and oils, which makes it work well in many different formulations. Its smell is fresh and green—like young leaves and branches—with light hints of wine, fruit, and fatty notes.
You can find it naturally in tiny amounts in things like citrus fruits, berries, tea leaves, geranium oil, various lavender oils, banana, apple, strawberry, and violet leaf oil—plus many other essential oils. Its esters show up right alongside it in these natural sources. All of this makes 1-Hexanol a really useful ingredient for creating flavors and fragrances.

Product Application of 1-Hexanol CAS#111-27-3
1-Hexanol is a popular flavor ingredient and also serves as a building block for essential oils like geranium oil, where it helps create the top notes in perfumes. You can also add just a tiny bit to violet, osmanthus, magnolia, and ylang-ylang flavor blends to give them a fresh, green, leafy character.
It's also used in small amounts in coconut, berry, and many fruit flavor formulas. Beyond flavor work, 1-Hexanol works as a solvent and lab reagent, and it's used in making pharmaceuticals—especially preservatives and sedatives.
China's GB2760-86 regulations approve 1-Hexanol as a food flavoring, mainly for coconut and berry flavors. It's also used to make surfactants, plasticizers, and fatty alcohols, and it's a handy reagent for chromatography and an intermediate for organic synthesis.
