Description

1,16-Hexadecanedithiol, 99% is a high-purity, long-chain aliphatic dithiol compound. This bifunctional molecule is valued for its ability to act as a versatile linker and surface modifier, forming stable bonds with metals and other substrates. It is essential for researchers and manufacturers in the fields of nanotechnology, materials science, and specialty polymer synthesis who require precise molecular building blocks.

Application

• Self-Assembled Monolayer (SAM) Formation: Used to create ordered molecular films on gold, silver, and other metal surfaces for corrosion inhibition, biosensor development, and surface patterning.
• Nanoparticle Capping and Stabilization: Acts as a stabilizing ligand for metal and semiconductor nanoparticles (e.g., quantum dots), controlling their size, dispersion, and surface chemistry.
• Polymer Modification and Crosslinking: Serves as a chain extender or crosslinking agent in the synthesis of polyurethanes, polysulfides, and other specialty polymers to enhance mechanical properties.
• Surface Functionalization: Modifies the surface properties of materials like carbon nanotubes, graphene, and oxides to improve compatibility in composite materials.
• Lubricant Additive: Functions as an extreme pressure (EP) and anti-wear additive in advanced lubricant formulations due to its ability to form protective films on metal surfaces.
• Chemical Synthesis Intermediate: A key precursor in organic synthesis for creating macrocycles, dendrimers, and other complex molecular architectures.

Quality Control

Our 1,16-Hexadecanedithiol, 99% is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including chromatographic purity assays and identity confirmation, to ensure it meets the declared specification. A comprehensive Certificate of Analysis (COA) detailing purity, physical properties, and test results is provided with every shipment to guarantee traceability and consistency for your critical applications.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at room temperature (15-25°C) in a cool, dry, well-ventilated place. Due to its thiol functionality, it is easily oxidized; ensure containers are properly sealed after each use to minimize exposure to air.
