Description

1,9-Diiodononane is a high-purity, linear aliphatic diiodoalkane building block of significant interest in advanced organic synthesis and materials science. Its bifunctional nature, featuring two reactive iodine termini, makes it a versatile precursor for constructing longer-chain molecules, polymers, and complex molecular architectures. This compound is particularly valuable for researchers and manufacturers in the pharmaceutical, agrochemical, and specialty polymer industries seeking reliable, high-quality intermediates for coupling reactions and material modification.

Application

• Pharmaceutical Intermediate: Serves as a key building block in the synthesis of active pharmaceutical ingredients (APIs), particularly for creating long-chain linkers or spacers.
• Agrochemical Synthesis: Used in the production of specialized pesticides and herbicides where specific chain length and terminal functionality are required.
• Polymer & Material Science: Acts as a monomer or chain extender in the synthesis of specialty polymers, liquid crystals, and functional materials.
• Cross-coupling Reactions: An essential substrate in various metal-catalyzed cross-coupling reactions (e.g., Negishi, Kumada) to form carbon-carbon bonds.
• Organic Synthesis Reagent: Employed as a reliable alkylating agent or a precursor for generating other functional groups like alkenes or alcohols.
• Surface Modification: Used to functionalize surfaces or nanoparticles by introducing long alkyl chains with terminal reactive sites.
• Ligand & Catalyst Preparation: Useful in the synthesis of complex ligands or organometallic catalysts for asymmetric synthesis.
• Research & Development: A critical tool in academic and industrial R&D for exploring new synthetic methodologies and novel compound libraries.

Quality Control

Our 1,9-Diiodononane is produced under stringent quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including HPLC for assay and impurity profiling, GC for residual solvents, and NMR for structural confirmation. A detailed Certificate of Analysis (COA) documenting purity, identity, and specific tests is provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Keep away from heat, sparks, and open flame. Due to its light-sensitive nature, containers should be amber-colored or stored in opaque secondary packaging.
