Description

Octamethylene Bis(Methanethiosulfonate) is a specialized bifunctional thiosulfonate compound with a defined eight-carbon spacer chain. This molecular structure makes it a valuable cross-linking agent and chemical modifier in advanced material synthesis and bioconjugation chemistry. It is primarily utilized by research institutions, pharmaceutical developers, and specialty polymer manufacturers for creating novel materials with tailored properties.

Application

• Bioconjugation and Protein Modification: Acts as a homobifunctional cross-linker for introducing disulfide bonds or for site-specific labeling of proteins and peptides.
• Polymer Chemistry: Serves as a chain extender or cross-linking monomer in the synthesis of specialty polymers, such as polysulfides or functionalized polyurethanes.
• Material Science: Used to modify surface properties of materials or to create self-assembled monolayers (SAMs) on gold and other surfaces.
• Pharmaceutical Research: Employed in drug discovery for linker technology in antibody-drug conjugates (ADCs) or prodrug design.
• Chemical Synthesis Intermediate: Functions as a key building block for synthesizing more complex sulfur-containing organic molecules.
