Description

n-(Triethoxysilylpropyl)Dansylamide is a specialized organosilane derivative that combines a reactive triethoxysilyl group with the highly fluorescent dansylamide moiety. This unique bifunctional structure is critical for creating covalent, fluorescent linkages to surfaces, enabling precise tracking and analysis in advanced material science. It is primarily utilized by researchers and manufacturers in the fields of analytical chemistry, sensor development, and the surface modification of inorganic substrates like glass, silica, and metals.

Application

• Fluorescent Labeling Agent: Used to tag and visualize surfaces, particles, or biomolecules for detection and imaging applications.
• Sensor Development: Acts as a key component in the fabrication of optical chemical sensors and biosensors due to its environment-sensitive fluorescence.
• Surface Modification: Covalently bonds to hydroxylated surfaces (e.g., glass, quartz, silicon wafers) to introduce stable fluorescent properties for studies in adhesion, coatings, and composite materials.
• Chromatography: Employed in the development of stationary phases for high-performance liquid chromatography (HPLC) and thin-layer chromatography (TLC).
• Bioconjugation & Probes: Serves as a linker for attaching fluorescent probes to proteins, antibodies, or other biological molecules in diagnostic assays.
• Materials Research: Utilized in the study of sol-gel processes, hybrid organic-inorganic materials, and smart coatings where a traceable silane coupling agent is required.
