Description

(5Z,9Z,13Z)-6,10,14,18-Tetramethylnonadeca-5,9,13,17-Tetraen-2-One CAS NO 3796-67-6 is a high-purity, long-chain isoprenoid ketone, also known as a farnesylacetone derivative. This compound is a critical intermediate in the synthesis of biologically active molecules, including vitamins, carotenoids, and pharmaceuticals. It is essential for R&D and production in the fine chemical, nutraceutical, and fragrance industries, where precise molecular structure and purity are paramount for successful outcomes.

Application

• Pharmaceutical Intermediate: A key building block in the synthesis of Vitamin K analogs, coenzyme Q10, and other terpenoid-based therapeutics.
• Fragrance & Flavor Synthesis: Serves as a precursor for creating specific woody, amber, and tobacco-like scent notes in high-end perfumery and flavor compounds.
• Nutraceutical Production: Used in the manufacture of carotenoids like lycopene and β-carotene, as well as other isoprenoid-based dietary supplements.
• Agrochemical Research: Employed as an intermediate in developing novel plant growth regulators and pheromones.
• Organic Synthesis & Catalysis: A valuable chiral synthon in academic and industrial research for constructing complex natural product frameworks.
• Material Science: Investigated for its potential in creating specialized polymers and liquid crystals due to its rigid, conjugated backbone.
