Description

T-Butyldimethyl(Undec-10-Ynyloxy)Silane is a specialized organosilicon compound featuring a terminal alkyne functional group. This unique molecular architecture makes it a valuable synthetic intermediate and coupling agent in advanced material science and pharmaceutical research. It is primarily needed by R&D chemists and process engineers in the fine chemical, polymer, and life sciences sectors for constructing complex molecular architectures.

Application

• Click Chemistry Reagent: The terminal alkyne group enables efficient Huisgen 1,3-dipolar cycloaddition (copper-catalyzed azide-alkyne cycloaddition, CuAAC) for bioconjugation and polymer functionalization.
• Surface Modification Agent: Used to create self-assembled monolayers (SAMs) on silicon, glass, or metal oxide surfaces, imparting specific hydrophobicity or reactivity for sensor and microfluidic device fabrication.
• Pharmaceutical Intermediate: Serves as a key building block in the synthesis of complex drug candidates, particularly where a silane-protected alkyne linker is required for further derivatization.
• Polymer & Dendrimer Synthesis: Acts as a functional monomer or cross-linking agent in the development of specialty silicones, hybrid organic-inorganic polymers, and dendritic structures.
• Material Science Research: Employed in the development of novel nanomaterials, including functionalized nanoparticles and advanced coatings with tailored surface properties.
• Protecting Group Chemistry: The tert-butyldimethylsilyl (TBDMS) group can be used to protect alcohols, though in this molecule it is part of the silane ether structure.

Quality Control

Our production of T-Butyldimethyl(Undec-10-Ynyloxy)Silane adheres to stringent internal quality standards to ensure batch-to-batch consistency and high purity for research and development applications. Each lot is characterized using advanced analytical techniques, including NMR, GC, and HPLC, to confirm identity and purity. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation. Keep away from incompatible materials such as strong bases and fluorides.
