Description

(2E,6E,10E,14E)-3,7,11,15,19-Pentamethylicosane-2,6,10,14,18-Pentaene-1-Ol is a high-purity, long-chain isoprenoid alcohol, also known as all-trans-farnesol. This compound serves as a critical intermediate and building block in the synthesis of complex organic molecules, including vitamins, fragrances, and pharmaceuticals. It is essential for manufacturers in the flavor & fragrance, cosmetic, and fine chemical industries seeking a reliable, high-quality raw material for their production processes.

Application

• Flavor and Fragrance Industry: A key intermediate in the synthesis of terpenoid-based aroma chemicals and perfumery ingredients.
• Pharmaceutical Synthesis: Used as a chiral building block for the production of vitamins (e.g., Vitamin E, K) and other bioactive compounds.
• Cosmetic Formulations: Employed in the creation of specialty ingredients for skincare and personal care products.
• Fine Chemical Manufacturing: Acts as a versatile precursor in organic synthesis for research and industrial-scale chemical production.
• Agrochemical Intermediates: Utilized in the development of certain plant growth regulators and specialty agrochemicals.
• Biochemical Research: Serves as a standard or substrate in studies of isoprenoid biosynthesis and metabolic pathways.
