Product Introduction
1,8-Octanedinitrile (CAS 629-40-3), commonly referred to as Sebaconitrile, is an organic dinitrile with the molecular formula C8H12N2. It appears as a colorless to slightly yellow liquid (or low-melting crystalline solid) at room temperature. As a linear alpha, omega-dinitrile, 1,8-Octanedinitrile (CAS 629-40-3) is a vital building block in the synthesis of long-chain aliphatic compounds. It is primarily valued for its role in the production of specialty polymers, lubricants, and pharmaceutical active ingredients where a stable eight-carbon chain is required.
Product Selling Points
-
Ultra-High Purity (≥ 99.0%): Chemfine ensures a strictly controlled distillation process to provide an exceptionally clean product for sensitive catalytic reactions.
-
Low Water Content (≤ 0.1%): Essential for use in polymerization and moisture-sensitive electrolyte applications to prevent side reactions.
-
Stable Carbon Chain: The linear C8 structure provides excellent thermal and chemical stability to resulting polymers and intermediates.
-
Optimal Precursor for Diamines: High conversion efficiency when hydrogenated to produce 1,8-diaminooctane, a key nylon monomer.
-
Versatile Chemical Reactivity: The dual nitrile groups allow for a wide range of transformations, including hydrolysis to sebacic acid or reduction to diamines.
-
Global Quality Standards: Manufactured under rigorous QA/QC protocols to ensure batch-to-batch consistency for industrial scale-up.
Applications
Polymer and Resin Manufacturing The primary use is as a precursor to 1,8-diaminooctane, which is a monomer for specialty polyamides (Nylon 8,8). These polymers exhibit superior moisture resistance and mechanical strength compared to shorter-chain nylons.
Pharmaceutical Intermediates Serves as a fundamental building block for the synthesis of complex macrocyclic compounds and specialized APIs, particularly those requiring a flexible aliphatic linker.
Electrochemical Applications Utilized as an additive in high-performance lithium-ion battery electrolytes to improve thermal stability and enhance safety by forming a protective layer on electrodes.
Specialty Lubricants and Plasticizers The derivatives of 1,8-Octanedinitrile are used in the formulation of high-temperature lubricants and specialized plasticizers for engineering plastics.
Corrosion Inhibitors Processed into various derivatives that act as effective corrosion inhibitors in metalworking fluids and industrial water treatment systems.
Packaging
Standard industrial packaging options for 1,8-Octanedinitrile include:

Storage
1,8-Octanedinitrile is a stable compound but should be stored in a cool, dry, and well-ventilated warehouse. Keep containers tightly sealed to prevent moisture absorption and contact with air. Store away from strong acids, strong bases, and powerful oxidizing agents. As it has a melting point near 7°C, it may solidify in colder environments; gentle heating may be required to restore the liquid state before use. Properly stored, it has a shelf life of 24 months.
