Description

Pss-Isocyanatopropyldimethylsilyloxy-He& CAS NO 352538-81-9 is a specialized organosilicon compound featuring a reactive isocyanate group and a silyl ether moiety. This dual functionality makes it a valuable bifunctional linker and coupling agent for advanced material synthesis. It is primarily used by R&D and production chemists in the pharmaceutical, specialty polymer, and surface modification industries to create novel hybrid materials with tailored properties.

Application

• Surface Modification Agent: Used to functionalize glass, silica, and other inorganic surfaces with reactive isocyanate groups for subsequent covalent attachment of biomolecules or polymers.
• Polymer Crosslinking: Acts as a crosslinker in polyurethane and silicone-based polymer systems to enhance mechanical strength and thermal stability.
• Pharmaceutical Intermediates: Serves as a key building block in the synthesis of drug conjugates and prodrugs, particularly for targeted drug delivery systems.
• Hybrid Material Synthesis: Enables the creation of organic-inorganic hybrid materials (ORMOSILs) for coatings, adhesives, and advanced composites.
• Chromatography Media: Employed in the derivatization of stationary phases for HPLC and affinity chromatography to achieve specific separation properties.
• Adhesive and Sealant Formulations: Incorporated as an adhesion promoter and moisture-curing component in high-performance sealants and adhesives.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a recommended temperature of 2-8°C. Due to its hygroscopic (moisture-sensitive) nature, containers must be kept sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation. Keep away from heat, sparks, and open flame.
