Description

1,9-Nonanedithiol is a high-purity, linear aliphatic dithiol compound, a critical building block for synthesizing advanced materials with tailored properties. Its bifunctional nature, featuring two reactive thiol (-SH) groups, makes it an essential monomer for creating polymers with specific chain lengths and functionalities. This product is particularly valuable for researchers and manufacturers in the polymer, nanotechnology, and specialty chemical sectors seeking to develop novel materials with precise molecular architectures.

Application

• Polymer Synthesis: Key monomer for the production of polyurethanes, polyesters, and other step-growth polymers requiring a defined, linear di-thiol spacer.
• Nanomaterial Functionalization: Used as a surface ligand or crosslinker for gold nanoparticles (AuNPs), quantum dots, and other nanomaterials due to its strong gold-thiolate bond and defined chain length.
• Self-Assembled Monolayers (SAMs): Employed in creating ordered molecular films on metal surfaces for applications in sensors, corrosion inhibition, and surface patterning.
• Pharmaceutical Intermediates: Serves as a versatile synthetic intermediate in the development of drug candidates and bioactive molecules containing disulfide or thioether linkages.
• Adhesive & Sealant Formulations: Acts as a chain extender or crosslinking agent in high-performance adhesive systems, enhancing flexibility and chemical resistance.
• Chelating Agent Precursor: Used to synthesize ligands for metal ion chelation in catalysis or extraction processes.

Quality Control

Our 1,9-Nonanedithiol is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including chromatography (GC/HPLC) and spectroscopic methods, to ensure high purity and consistency. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment to support your quality assurance and R&D documentation needs.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at 2-8°C to minimize oxidation and prolong shelf life. Keep away from strong oxidizing agents and bases. Allow the container to reach ambient temperature before opening to prevent moisture condensation.
