Description

Propargyl-3-Sulfopropyl Ether Sodium Salt is a versatile organosulfur compound featuring both a sulfonate group and a terminal alkyne functionality. This unique bifunctional structure makes it a valuable intermediate for click chemistry, surface modification, and the synthesis of specialized polymers and surfactants. It is particularly sought after by researchers and manufacturers in the pharmaceutical, materials science, and specialty chemical industries for creating advanced functional materials and bioactive conjugates.

Application

• Click Chemistry Intermediate: The terminal alkyne group enables efficient copper-catalyzed azide-alkyne cycloaddition (CuAAC) reactions for bioconjugation and polymer synthesis.
• Surface Modifier & Zwitterionic Monomer: Used to create sulfobetaine-type zwitterionic surfaces on materials (e.g., gold, silica) to impart anti-fouling, hydrophilic, and biocompatible properties.
• Specialty Surfactant Synthesis: Serves as a key building block for synthesizing novel anionic and zwitterionic surfactants with specific performance characteristics.
• Polymer & Hydrogel Functionalization: Incorporated into polymer backbones or used to cross-link hydrogels, enhancing water solubility, ionic conductivity, or biological activity.
• Pharmaceutical & Biotech Research: Employed in the development of drug delivery systems, diagnostic probes, and protein-polymer conjugates via its reactive alkyne handle.
• Electroplating Additive: Can function as a brightener or leveling agent in specific electroplating formulations due to its sulfur-containing structure.
