Description

4-(((3-Cholesteryloxy)Carbonyl)Amino)-5-Hydroxy-2,7-Naphthalenedisulfonic Acid CAS NO 158721-72-3 is a sophisticated cholesteryl-derivatized naphthalene disulfonic acid compound, designed for advanced research and high-precision applications. This specialized chemical is valued for its unique amphiphilic structure, which combines a hydrophobic sterol moiety with a hydrophilic, multi-charged aromatic sulfonic acid core. It is primarily sought by researchers and developers in the life sciences and advanced materials sectors for its utility as a functional building block or probe in complex chemical systems.

Application

• Biomimetic Membrane Research: As a functionalized sterol derivative, it serves as a key component in the synthesis of novel amphiphiles for studying membrane dynamics, lipid raft formation, and cholesterol trafficking mechanisms.
• Advanced Material Synthesis: Utilized as a precursor or dopant in creating specialized polymers, liquid crystals, or self-assembling materials where the introduction of both sulfonic acid groups and a sterol framework is required.
• Diagnostic Reagent Development: Its strong chromophore and potential for derivatization make it a candidate for developing fluorescent probes, sensors, or colorimetric assay reagents in biochemical analysis.
• Surface Modification & Coatings: Acts as a surface-active agent or anchor for modifying material surfaces to impart specific wetting, anti-fouling, or ion-exchange properties.
• Pharmaceutical Intermediates: Employed in the research and development of novel drug candidates, particularly those targeting lipid metabolism or requiring targeted delivery systems.
• Chromatography & Separation Science: Can be used as a chiral selector or a stationary phase modifier in chromatographic techniques due to its complex, structured moiety.
