Description

11-(Pyrene-1-Sulfonylamino)Undecanoic Acid is a specialized organic compound that serves as a versatile building block and functional linker in advanced material science and life science research. Its molecular architecture, featuring a pyrene fluorophore connected to an undecanoic acid chain via a sulfonylamino bridge, enables unique photophysical properties and surface functionalization capabilities. This compound is primarily utilized by researchers and product developers in the fields of fluorescence labeling, sensor development, and the creation of self-assembled monolayers (SAMs) for surface modification.

Application

• Fluorescent Labeling and Probes: Acts as a hydrophobic, long-chain fluorescent tag for labeling biomolecules, polymers, or nanoparticles for detection and imaging applications.
• Chemical Sensor Development: Used in the synthesis of pyrene-based chemosensors for detecting ions or small molecules due to its excimer formation properties.
• Surface Functionalization: The carboxylic acid terminus allows for covalent attachment to surfaces (e.g., gold, silica, oxides) to create functionalized interfaces for studies in adhesion, corrosion inhibition, or biocompatibility.
• Polymer and Material Science: Incorporated as a monomer or additive to impart fluorescence or modify the surface properties of polymers and composite materials.
• Supramolecular Chemistry: Serves as a building block for constructing complex molecular architectures, gels, or liquid crystals that leverage π-π stacking of the pyrene units.
• Chromatography and Separation Science: Can be used to derivatize stationary phases to alter selectivity in chromatographic separations.
