Description

Triphenyl[(2E,6E,10E)-3,7,11,15-Tetramethyl-2,6,10,14-Hexadecatetraenyl]Phosphonium Bromide is a high-purity, synthetic phosphonium salt derivative of farnesol, serving as a critical Wittig reagent in advanced organic synthesis. Its primary value lies in enabling the stereoselective construction of polyene chains, a key structural motif in biologically active compounds. This specialized reagent is essential for researchers and manufacturers in pharmaceutical development, particularly for synthesizing retinoids, carotenoids, and other complex isoprenoid-based molecules.

Application

• Pharmaceutical Intermediate Synthesis: Key reagent for the stereocontrolled synthesis of vitamin A analogs, retinoids, and other therapeutic agents targeting nuclear receptors.
• Fine Chemical Production: Used in the construction of complex polyene backbones for specialty chemicals, flavors, and fragrances.
• Academic & Industrial Research: A vital tool in medicinal chemistry and total synthesis projects for building specific carbon-carbon double bonds via the Wittig olefination reaction.
• Nutraceutical Precursor Development: Employed in the research and development of carotenoid and other isoprenoid-based nutritional supplements.
• Material Science Research: Potential use in synthesizing organic semiconductors or light-harvesting materials with extended conjugated systems.
