Product Application of 1-Hexanol (CAS# 111-27-3)
1-Hexanol is widely used as a flavoring base and in the formulation of essential oils, such as geranium oil, where it contributes to top-note characteristics. It is also used in trace amounts in violet, osmanthus, magnolia, and ylang-ylang fragrances to enhance or impart a fresh green and delicate aroma.
In food flavor applications, it is added in very small amounts to coconut, berry, and various fruit flavor formulations. It is also used as a solvent and analytical reagent, and in the pharmaceutical industry for the preparation of preservatives and sedative-related products.
According to GB2760-86 regulations in China, it is an approved edible flavoring substance, primarily used in coconut and berry flavor formulations. In addition, it is applied in the production of surfactants, plasticizers, and fatty alcohols, and serves as a reagent in chromatographic analysis as well as in various organic synthesis processes.
