Description

Azido-PEG3-triethoxysilane is a heterobifunctional crosslinker featuring an azide group for click chemistry and a triethoxysilane moiety for surface modification. This compound matters for its ability to create stable, covalent linkages between organic molecules and inorganic substrates like glass, silicon, or metal oxides. It is essential for researchers and manufacturers in bioconjugation, surface engineering, and materials science who require precise and robust functionalization strategies.

Application

• Surface Functionalization: Immobilization of biomolecules, dyes, or polymers onto glass, silica, or silicon wafers for biosensor and microarray development.
• Bioconjugation Linker: Serves as a versatile spacer arm for conjugating azide-modified biomolecules (via click chemistry) to silanized surfaces or particles.
• Materials Science: Modification of nanoparticles (e.g., silica NPs) and quantum dots to introduce azide handles for further click chemistry reactions.
• Polymer Chemistry: Incorporation into hybrid organic-inorganic polymers or as a coupling agent in sol-gel processes to introduce reactive azide groups.
• Adhesion Promotion: Used as an advanced silane coupling agent to improve adhesion between organic resins and inorganic fillers or substrates.
• Diagnostic Assays: Fabrication of stable, functionalized surfaces for diagnostic devices and lab-on-a-chip applications.

Quality Control

Our Azido-PEG3-triethoxysilane is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including NMR, HPLC, and FT-IR, to confirm identity, purity, and functional group integrity. Certificates of Analysis (COA) with detailed specifications are available upon request to ensure compliance with your research and production standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 2-8°C or as indicated on the label. This material is hygroscopic (moisture-sensitive); keep the container tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to maintain stability and prevent hydrolysis of the silane group.
