As a premier manufacturer and supplier of specialty chemicals, NINGBO INNO PHARMCHEM CO.,LTD. understands the critical role such reagents play in cutting-edge research. If you are looking to buy 4,4'-Dipyridyl Disulfide, understanding its applications can help guide your purchasing decisions.

What is 4,4'-Dipyridyl Disulfide?

4,4'-Dipyridyl Disulfide, identified by CAS number 2645-22-9, is an organic compound characterized by its pale yellow powder appearance and a typical purity of 98%. Its molecular formula is C10H8N2S2, with a molecular weight of approximately 220.31 g/mol. The disulfide bond within its structure is key to its reactivity and functionality.

Applications in Gold Surface Modification

The primary utility of 4,4'-Dipyridyl Disulfide lies in its ability to readily chemisorb onto gold surfaces. The sulfur-gold interaction forms strong, stable bonds, allowing for the creation of self-assembled monolayers (SAMs). This process is vital for numerous applications, including:

  • Biomolecule Immobilization: Researchers often purchase 4,4'-Dipyridyl Disulfide to create functionalized gold surfaces for immobilizing proteins, antibodies, DNA, or other biomolecules. This is a cornerstone for developing biosensors, diagnostic platforms, and lab-on-a-chip devices.
  • Surface Characterization: Modified surfaces are essential for techniques like surface plasmon resonance (SPR) or atomic force microscopy (AFM) to study molecular interactions and surface properties.

For scientists needing to buy 4,4'-Dipyridyl Disulfide for these applications, ensuring high purity is non-negotiable to achieve reproducible results. Sourcing from a reliable manufacturer like NINGBO INNO PHARMCHEM CO.,LTD. guarantees the quality required.
