Description

1-Undecanesulfonic Acid, 11-Mercapto-, Sodium Salt (1:1) is a specialized organosulfur compound featuring both a sulfonate and a terminal thiol functional group. This unique bifunctional structure makes it a valuable intermediate for synthesizing surfactants, ligands, and functional polymers with tailored surface-active or metal-binding properties. It is primarily sought by research and development teams in the specialty chemical, pharmaceutical, and advanced materials sectors for creating novel compounds and formulations.

Application

• Specialty Surfactant Synthesis: Acts as a key intermediate for producing novel anionic surfactants with specific chain lengths and reactive thiol handles for further modification.
• Pharmaceutical Intermediates: Used in the research and development of active pharmaceutical ingredients (APIs) or prodrugs where a sulfonate and thiol group are required for activity or conjugation.
• Polymer Modification & Functionalization: Serves as a monomer or grafting agent to introduce sulfonate and thiol functionalities into polymers, enhancing properties like hydrophilicity, adhesion, or cross-linking capability.
• Ligand and Chelating Agent Precursor: The thiol group makes it a valuable starting material for synthesizing ligands used in catalysis, metal recovery, or nanotechnology.
• Surface Coating Additives: Employed in formulating advanced coatings to improve surface wetting, adhesion promotion, or to create self-assembled monolayers (SAMs).
• Analytical Chemistry Reagents: Utilized as a derivatization agent or a standard in chromatographic analysis and other laboratory methodologies.

Quality Control

Our 1-Undecanesulfonic Acid, 11-Mercapto-, Sodium Salt (1:1) is manufactured under strict quality management protocols. Each batch undergoes rigorous analytical testing to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing key specifications such as assay, impurity profile, and physical characteristics are provided and available upon request to support your quality assurance processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at a controlled room temperature (typically 15-25°C). Due to its thiol group, this compound is easily oxidized; for long-term storage, maintaining an inert atmosphere (e.g., under nitrogen or argon) is recommended to preserve stability and purity. Keep away from strong oxidizing agents.
