Description

1,7-Diiodoheptane is a high-purity, linear aliphatic diiodoalkane building block essential for advanced organic synthesis and materials science. Its bifunctional structure, featuring two reactive iodine termini, makes it a versatile precursor for creating extended molecular chains and functional polymers. This compound is particularly valuable for researchers and manufacturers in the pharmaceutical, agrochemical, and specialty polymer industries seeking to develop novel compounds with specific chain lengths and properties.

Application

• Pharmaceutical Intermediate: Serves as a key building block in the synthesis of active pharmaceutical ingredients (APIs), particularly for creating long-chain linkers and spacers.
• Agrochemical Synthesis: Used in the production of herbicides, fungicides, and plant growth regulators requiring specific aliphatic chain modifications.
• Polymer & Material Science: Acts as a monomer or chain extender in the synthesis of specialty polymers, liquid crystals, and organic electronic materials.
• Crosslinking Agent: Employed in the formulation of resins, elastomers, and coatings to introduce crosslinks and modify material properties.
• Organic Synthesis Reagent: A valuable reagent in coupling reactions (e.g., Ullmann, Kumada) and for introducing iodine functional groups into complex molecules.
• Liquid Crystal Precursor: Used in the development of mesogenic compounds for display technologies.
• Research & Development: Essential for academic and industrial R&D in medicinal chemistry and novel material discovery.

Quality Control

Our 1,7-Diiodoheptane is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, GC, and NMR, to ensure high chemical purity and consistency. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are provided with every shipment to support your quality assurance and regulatory compliance needs.

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). Due to its light-sensitive and highly volatile nature, containers should be kept sealed and away from heat sources and strong oxidizing agents.
