Description

1-Bromo-11-Iodoundecane is a high-purity, bifunctional halogenated alkane building block of significant importance in advanced organic synthesis. Its distinct structure, featuring terminal bromine and iodine atoms separated by a long alkyl chain, makes it a versatile precursor for creating complex molecular architectures. This compound is essential for researchers and manufacturers in the pharmaceutical, materials science, and specialty chemical industries who require precise, multi-step synthetic pathways.

Application

• Pharmaceutical Intermediate: A key building block for the synthesis of complex drug candidates, particularly in creating long-chain linkers or modifying bioactive molecules.
• Liquid Crystal & Advanced Material Synthesis: Used in the preparation of monomers and precursors for functional polymers, liquid crystals, and organic electronic materials.
• Cross-Coupling Reactions: Serves as a valuable substrate in palladium-catalyzed reactions (e.g., Heck, Sonogashira, Suzuki) due to its dual, differentially reactive halogen termini.
• Surface Modification & Nanotechnology: Employed to functionalize surfaces, nanoparticles, and polymers through thiol-ene "click" chemistry or other coupling strategies.
• Bioconjugation & Probe Development: Useful for labeling biomolecules or creating fluorescent or radioactive probes for diagnostic and research applications.
• Macrocycle & Dendrimer Construction: Acts as a spacer or linker unit in the synthesis of cyclic compounds and dendritic structures.
