Description

4-[2-(Trimethoxysilyl)Ethyl]Benzene-1-Sulphonyl Azide is a specialized bifunctional organosilicon reagent that combines a reactive sulfonyl azide group with a hydrolyzable trimethoxysilyl moiety. This unique structure makes it a critical intermediate for surface modification and covalent cross-linking applications, enabling the introduction of azide functionalities onto silicon-based substrates. It is essential for researchers and manufacturers in advanced materials science, particularly for developing functionalized polymers, adhesion promoters, and bio-conjugation platforms.

Application

• Surface Functionalization Agent: Used to covalently attach azide groups to silica, glass, or other hydroxylated surfaces for subsequent "click chemistry" reactions.
• Cross-linking Agent for Polymers: Serves as a key component in the synthesis of cross-linked silicone polymers and elastomers with tailored properties.
• Adhesion Promoter: Enhances the bonding between organic polymers and inorganic substrates in composite materials and coatings.
• Bioconjugation Linker: Facilitates the immobilization of biomolecules (e.g., proteins, peptides) onto solid supports for biosensor and diagnostic device development.
• Intermediate for Specialty Silanes: Acts as a precursor for synthesizing more complex silane coupling agents with photoactive or thermally reactive azide handles.
• Research & Development: Employed in academic and industrial R&D for exploring new material interfaces and polymer networks via Huisgen cycloaddition.

Quality Control

Our production of 4-[2-(Trimethoxysilyl)Ethyl]Benzene-1-Sulphonyl Azide adheres to stringent internal quality protocols to ensure batch-to-batch consistency and high purity. Each lot is analyzed using advanced chromatographic and spectroscopic techniques. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at temperatures between 2°C and 8°C (refrigerated) to maintain stability. Due to its light-sensitive and potentially shock-sensitive azide group, handle with appropriate precautions and avoid exposure to heat, strong acids, and heavy metals.
