Description

Biphenyl-4,4'-Dithiol is a high-purity organic compound featuring two thiol (-SH) groups on a biphenyl core, making it a versatile building block and linker molecule. Its primary value lies in its ability to form stable self-assembled monolayers (SAMs) and act as a crucial ligand or cross-linking agent in advanced materials. This product is essential for researchers and manufacturers in nanotechnology, electronics, and materials science who require precise molecular control for surface functionalization and device fabrication.

Application

• Formation of self-assembled monolayers (SAMs) on gold, silver, and other metal surfaces for sensor development and corrosion inhibition.
• Key precursor and cross-linking agent in the synthesis of conductive polymers, organic semiconductors, and advanced composite materials.
• Surface modification and functionalization of nanoparticles, quantum dots, and carbon nanotubes to tailor their chemical and physical properties.
• As a bidentate ligand in coordination chemistry for creating metal-organic frameworks (MOFs) and catalysts.
• Building block for liquid crystals and organic light-emitting diodes (OLEDs) due to its rigid biphenyl structure.
• Research and development of molecular electronics, including molecular wires and switches.
• Intermediate in pharmaceutical research and fine chemical synthesis.

Quality Control

Our Biphenyl-4,4'-Dithiol is produced under strict quality management protocols to ensure batch-to-batch consistency and high purity. We employ advanced analytical techniques, including HPLC, GC, and NMR, to verify identity and quantify impurities. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with each shipment to support your quality assurance and regulatory 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 degradation. The container should be kept in a cool, dry, and well-ventilated area, away from incompatible materials such as strong oxidizing agents.
