Description

11-Mercapto-1-undecanol is a bifunctional organic compound featuring both a terminal thiol (-SH) and a terminal hydroxyl (-OH) group on a long alkyl chain. This unique structure makes it a valuable intermediate for creating self-assembled monolayers (SAMs) and for surface modification in advanced materials science. It is particularly sought after by researchers and manufacturers in the nanotechnology, electronics, and specialty polymer sectors. The compound's dual functionality allows for precise control over surface properties, enabling applications in biosensors, corrosion inhibition, and molecular electronics.

Application

• Surface Modification & Self-Assembled Monolayers (SAMs): Key precursor for creating ordered molecular films on gold, silver, and other metal surfaces for research and device fabrication.
• Nanotechnology & Microfabrication: Used in the patterning and functionalization of surfaces for biosensors, lab-on-a-chip devices, and electronic components.
• Polymer & Material Science: Serves as a chain transfer agent or cross-linking modifier in the synthesis of specialty polymers and functional materials.
• Lubricant & Additive Intermediate: Employed in the development of extreme-pressure additives and high-performance lubricants due to its sulfur content.
• Corrosion Inhibition: Forms protective layers on metal surfaces, acting as a corrosion inhibitor in specialized coatings.
• Bioconjugation & Pharmaceutical Research: Utilized as a linker molecule for attaching biomolecules or drugs to surfaces or carrier systems in diagnostic and therapeutic research.

Quality Control

Our 11-Mercapto-1-undecanol is produced under strict quality management protocols to ensure batch-to-batch consistency and high purity for research and industrial applications. Each lot is analyzed using advanced techniques including GC, HPLC, and NMR to verify identity, purity, and the absence of critical impurities. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with every shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at 2-8°C to minimize oxidation of the thiol group and ensure long-term stability. Keep the container in a cool, dry, and well-ventilated place away from strong oxidizing agents.
