Description

3-Cyclohexene-1,2-dimethanol, 3,6-dimethyl-5-[2-methyl-4-(2,6,6-trimethyl-1-cyclohexen-1-yl)-1,3-butadienyl]-6-[4-methyl-6-(2,6,6-trimethyl-1-cyclohexen-1-yl)-1,3,5-hexatrienyl]-, cis-2,cis-5- (8CI) is a high-purity, complex organic intermediate with a unique polyene structure derived from vitamin A and ionone chemistry. This compound is valued for its role as a key synthon in the production of specialized carotenoids, retinoids, and other high-value fine chemicals. It is essential for R&D and manufacturing in the pharmaceutical, nutraceutical, and specialty fragrance sectors, where precise molecular architecture is critical for biological activity and sensory properties.

Application

• Pharmaceutical Intermediate: Serves as a critical building block in the synthesis of novel retinoid-based therapeutics and vitamin A analogs for dermatology and oncology research.
• Nutraceutical Synthesis: Used in the production of advanced carotenoid derivatives and specialized forms of vitamin A for dietary supplements.
• Fine Fragrance & Aroma Chemicals: Acts as a precursor for high-value ionone and damascone derivatives, imparting unique woody, floral, and fruity notes in premium perfumery.
• Advanced Material Research: Investigated as a monomer or additive for creating organic semiconductors and light-harvesting materials due to its extended conjugated system.
• Agrochemical Intermediates: Potential use in developing novel plant growth regulators or protective agents leveraging its structural similarity to natural products.
• Chemical Reference Standard: Supplied as a high-purity standard for analytical method development and quality control in related chemical processes.
