Description

3-(Isocyanato)Propyl-Functionalized Silica Gel is a high-performance, organically modified inorganic material where an isocyanate-terminated propyl group is covalently bonded to a silica gel matrix. This functionalization is critical for creating reactive, high-surface-area supports used in advanced material synthesis and separation science. It is primarily utilized by researchers and manufacturers in the pharmaceutical, polymer, and specialty chemical industries for applications requiring selective binding, catalysis, or surface modification.

Application

• Solid-Phase Synthesis Support: Acts as a reactive solid support for the immobilization of amines, alcohols, and other nucleophiles in combinatorial chemistry and peptide synthesis.
• Chromatography Stationary Phase: Serves as a precursor for manufacturing specialized HPLC or affinity chromatography media with tailored surface chemistry.
• Polymer Modification & Composite Fillers: Used as a coupling agent or reactive filler to enhance the interfacial adhesion and mechanical properties in polyurethane and other polymer composites.
• Catalyst & Ligand Immobilization: Provides a stable, high-surface-area platform for anchoring homogeneous catalysts or ligands, facilitating catalyst recovery and reuse.
• Sensor Development: Employed in the fabrication of chemical sensors and biosensors where the isocyanate group is used to covalently attach specific receptor molecules.
• Surface Engineering: Applied to modify the surface properties of materials for controlled wettability, adhesion, or to introduce specific chemical functionality.

Quality Control

Our 3-(Isocyanato)Propyl-Functionalized Silica Gel is manufactured under a strict quality management system. Each batch is characterized to ensure consistent functional group loading, particle size distribution, and surface area. Certificates of Analysis (COA) detailing key parameters such as isocyanate content, moisture level, and mesh size are available upon request to support your quality assurance protocols.

Storage

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