Description

Dodecyl Methanethiosulfonate is a specialized organosulfur compound with a long-chain alkyl group, serving as a versatile chemical intermediate and modifying agent. Its primary value lies in its ability to act as a thiol-specific alkylating agent, enabling controlled functionalization of proteins, peptides, and other sulfur-containing molecules. This product is essential for researchers and manufacturers in the fields of bioconjugation, proteomics, and materials science, where precise surface modification and cross-linking are required.

Application

• Bioconjugation Reagent: For site-specific modification of cysteine residues in proteins and antibodies for drug delivery and diagnostic applications.
• Proteomics Research: Used in activity-based protein profiling (ABPP) and the study of thiol-dependent enzyme mechanisms.
• Polymer Modification: Acts as a chain transfer agent or functional monomer in the synthesis of specialty polymers with tailored surface properties.
• Surface Engineering: Facilitates the creation of self-assembled monolayers (SAMs) on gold and other surfaces for sensor development.
• Cross-linking Agent: Enables the formation of disulfide bridges or thioether linkages in biomaterials and hydrogels.
• Chemical Synthesis Intermediate: A key building block for synthesizing more complex sulfur-containing surfactants and ligands.
