What is 4-Sulfocalix[4]arene sodium salt?

The Uses of 4-Sulfocalix[4]arene sodium salt

4-Sulfocalix[4]arene sodium salt is an amphiphilic calix[n]arene that can be used as a coupling agent for organic molecules and metal complexes because of its hydrophobic (aromatic ring) and hydrophilic (SO^3-) environments.

What are the applications of Application

4-Sulfocalix[4]arene sodium salt is a water-soluble calixarene complexing agent

General Description

4-Sulfocalix[4]arene is a cyclic oligomer, which is prepared by hydroxyalkylation of phenol and aldehyde. It belongs to the family of calixarenes with repeating phenolic units connected via methylene groups forming a macrocyclic molecule. It has an amphiphilic nature with different functional groups that make it useful in drug delivery systems. It shows potential applications in various fields such as analysis and separation, enzyme mimetic systems and self-assembly membranes.
