Description

(1S)-3,5,5-trimethyl-4-[(1E,3E,5E,7E,9E,11E,13E,15E,17E)-3,7,12,16-tetramethyl-18-(2,6,6-trimethyl-1-cyclohexenyl)octadeca-1,3,5,7,9,11,13,15,17-nonaenyl]cyclohex-3-en-1-ol is a high-purity, optically active carotenoid derivative. This compound is valued for its role as a key intermediate in the synthesis of complex natural products and specialty fine chemicals. It is primarily sought by research institutions and manufacturers in the pharmaceutical, nutraceutical, and advanced material sectors for developing novel formulations and bioactive molecules.

Application

• Pharmaceutical Intermediate: Serves as a critical building block in the synthesis of retinoid analogs and other vitamin A-related active pharmaceutical ingredients (APIs).
• Nutraceutical Research: Used in the development of advanced carotenoid-based supplements and functional food ingredients.
• Organic Synthesis: Acts as a versatile chiral synthon for constructing complex polyene structures in academic and industrial research.
• Cosmetic Ingredient Development: Employed in R&D for creating novel, stable derivatives with potential antioxidant or skin-conditioning properties.
• Biochemical Research: Utilized as a standard or probe in studies related to vision, cell differentiation, and signaling pathways involving retinoids.
• Material Science: Investigated for its potential application in organic semiconductors and light-harvesting materials due to its extended conjugated system.
