Description

9-(9-Anthroyloxy)Stearicacid (9-AS) is a specialized fluorescent fatty acid derivative, widely recognized as a vital molecular probe in biophysical and biochemical research. Its core value lies in its ability to incorporate into lipid membranes and report on membrane fluidity, phase transitions, and protein-lipid interactions through its anthracene-based fluorophore. This compound is essential for researchers and developers in the life sciences, particularly those working in membrane biophysics, analytical chemistry, and pharmaceutical formulation studies, where precise environmental sensing at the molecular level is required.

Application

• Fluorescent Membrane Probe: Used extensively to study lipid bilayer properties, including fluidity, microdomain formation (lipid rafts), and phase behavior in model and biological membranes.
• Biophysical Research: A key tool for investigating the interaction of peptides, proteins, and drugs with lipid membranes using fluorescence spectroscopy and microscopy techniques.
• Analytical Chemistry Standard: Serves as a reference or derivatization agent in chromatographic methods for the analysis of complex lipid mixtures.
• Sensor Development: Employed in the design of fluorescence-based sensors for detecting changes in local viscosity, polarity, and molecular order within confined systems.
• Material Science: Utilized in the development of advanced materials, such as smart polymers or nanostructures, where environment-responsive fluorescent reporting is needed.
