Product Description:

3-Octanol is a secondary aliphatic alcohol with the molecular formula C8H18O and a molecular weight of 130.23 g/mol. It features a hydroxyl group attached to the third carbon of an eight-carbon straight chain, existing as a colorless to pale yellow liquid with a characteristic fatty, mushroom-like, or earthy odor. Its primary application lies in the flavor and fragrance industry, where it is used as a synthetic aroma ingredient to impart green, herbal, and mushroom notes in perfumes, cosmetics, and food flavorings. It also serves as an intermediate in the synthesis of esters (e.g., 3-octyl acetate) for enhanced olfactory profiles. Additionally, 3-octanol functions as a defoaming agent in industrial processes and as a solvent or chemical intermediate in organic synthesis. As a versatile building block, it is employed in the preparation of specialty chemicals, plasticizers, and surfactants. It is flammable and should be handled with standard safety precautions, including storage away from heat sources and oxidizers.
