Product Application of 1-Hexanol CAS#111-27-3
1-Hexanol is extensively used as a flavoring ingredient and as a key raw material in the production of essential oils, including geranium oil, where it helps provide fresh top-note characteristics. In fragrance formulations, it can be incorporated in very small amounts into violet, osmanthus, magnolia, ylang-ylang, and other aromatic blends to enhance or create a natural green and delicate scent profile.
It is also applied in the formulation of coconut, berry, and various fruit flavors at low concentrations. Beyond flavor applications, 1-Hexanol serves as a useful solvent and analytical reagent and is utilized in the pharmaceutical sector for the synthesis of preservatives and sedative-related products.
In accordance with China’s GB2760-86 standard, 1-Hexanol is an approved edible flavoring substance, primarily used in coconut and berry flavor preparations. Furthermore, it acts as an important intermediate in the manufacture of surfactants, plasticizers, fatty alcohol derivatives, and other chemical products, while also being employed as a reagent for chromatographic analysis and organic synthesis.
