Description

(Azidomethyl)Phenethyltrimethoxysilane, Tech-90 is a specialized organosilicon compound featuring a reactive azidomethyl group. This unique bifunctional structure makes it a valuable coupling agent and surface modifier, enabling the introduction of azide functionality onto silicon-based materials. It is primarily used by R&D chemists and process engineers in the advanced materials, specialty polymers, and surface coating industries. The Tech-90 grade indicates a technical quality suitable for demanding industrial synthesis and formulation applications.

Application

• Surface Modification Agent: Used to functionalize silica, glass, and other inorganic surfaces with azide groups for subsequent click chemistry reactions (e.g., CuAAC).
• Adhesion Promoter: Enhances the bonding between organic polymers (like epoxies, polyurethanes) and inorganic substrates (metals, glass, minerals) in coatings, sealants, and composites.
• Crosslinking Agent: Serves as a reactive intermediate in the synthesis of crosslinked silicone polymers and hybrid organic-inorganic networks.
• Polymer Functionalization: Incorporated into polymer backbones or as an end-group to introduce azide functionality, enabling post-polymerization modification via azide-alkyne cycloaddition.
• Bioconjugation Linker: Utilized in research for attaching biomolecules (proteins, peptides, oligonucleotides) to silicon-based surfaces or particles in diagnostic and biosensor development.
• Silicone Resin Synthesis: Acts as a key monomer or modifier in the production of specialty silicone resins with tailored properties for high-performance materials.
